Unexpected formation of 4,7-dihalobenzo[b]thiophenes using Ohira-Bestmann reagent and reactivity of the halogen-substituted benzo[b]thiophenes in Suzuki-Miyaura coupling with phenylboronic acid

Reaction of 2-(1-adamantylsulfanyl)-3,6-dihalobenzaldehydes with Ohira-Bestmann reagent gave 4,7-dihalobenzo[b]thiophenes along with normal alkyne products. Nine types of 4,7-dihalobenzo[b]thiophenes bearing chlorine, bromine, or iodine atoms, were prepared by this method. Regioselectivity in Suzuki-Miyaura cross coupling reactions of the 4,7-dihalobenzo[b]thiophenes with PhB(OH)2 was also studied.

Nonsymmetrical 3,4-dithienylmaleimides by cross-coupling reactions with indium organometallics: Synthesis and photochemical studies

The synthesis and photochemical study of novel nonsymmetrical 1,2-dithienylethenes (DTEs) with a maleimide bridge have been carried out. The synthetic approach to the DTEs was based on successive selective palladium-catalyzed cross-coupling reactions of 5-susbtituted-2-methyl-3-thiophenyl indium reagents with 3,4-dichloromaleimides. The required organoindium reagents were prepared from 2-methyl-3,5-dibromothiophene by a selective (C-5) coupling reaction with triorganoindium compounds (R3In) and subsequent metal-halogen exchange. The coupling reactions usually gave good yields and have a high atom economy with substoichiometric amounts of R3In. The results of photochemical studies show that these novel dithienylmaleimides undergo a photocyclization reaction upon irradiation in the UV region and a photocycloreversion after excitation in the visible region, thus they can be used as photochemical switches. ON-OFF operations can be repeated in successive cycles without appreciable loss of effectiveness in the process.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 10243-15-9 is helpful to your research. Application of 10243-15-9

Synthesis and antitumor properties of N-[2- (dimethylamino)ethyl]carboxamide derivatives of fused tetracyclic quinolines and quinoxalines: A new class of putative topoisomerase inhibitors

A series of tetracyclic quinoline- and quinoxalinecarboxamides were prepared, and their cytotoxicities were evaluated in a series of murine human tumor cell lines. Most of the quinoline derivatives were prepared by an adaptation of the Pfitzinger synthesis, followed by thermal decarboxylation and coupling with N,N-dimethylethylenediamine via a mixed anhydride method using isobutyl chloroformate. The quinoline analogues showed cytotoxicities broadly similar to those of the known tricyclic acridine-4-carboxamide mixed topoI/II inhibitor DACA, with thieno and indeno analogues being the most active. They showed little decrease in potencies against the Jurkat human leukemia topo II-resistant lines JL(A) and JL(C), suggesting their cytotoxicity does not result primarily from inhibition of topo II. The quinoxaline analogues had more varied IC50 values, being on average less cytotoxic than the quinoline derivatives, but appeared to have a similar mode of action. Overall, this new class of compounds appear to be mixed topo I/II inhibitors, up to 3-fold more cytotoxic than DACA in the human leukemia cell lines studied, with in vivo activity in colon 38 comparable to that of DACA and doxorubicin.

One of the oldest and most widely used commercial enzyme inhibitors is aspirin, Safety of Benzo[b]thiophen-3(2H)-one, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 130-03-0

Intermolecular Reductive Heck Reaction of Unactivated Aliphatic Alkenes with Organohalides

A general intermolecular reductive Heck reaction of organohalides with both terminal and internal unactivated aliphatic alkenes has been first realized in high yield with complete anti-Markovnikov selectivity. The challenging vinyl bromides, aryl chlorides, and polysubstituted internal alkenes were first applied. More than 100 remote carbofunctionalized alkyl carboxylic acid derivatives were rapidly synthesized from easily accessible starting materials. The synthesis of drug molecules has further demonstrated the wide synthetic utility of this scalable strategy. Preliminary mechanistic studies are consistent with the proposed catalytic cycle.

Extending pi-conjugation system with benzene: An effective method to improve the properties of benzodithiophene-based polymer for highly efficient organic solar cells

To obtain a polymer based on benzodithiophene (BDT) owning both a largely extended pi-conjugation system and a low-lying highest occupied molecular orbital (HOMO), a polymer (PBDTBzT-DTffBT) containing benzothienyl-substituted BDT is designed and synthesized. Compared with the polymer (PBDTT-DTffBT) based on thienyl-substituted BDT, PBDTBzT-DTffBT exhibits better thermal stabilities, red-shifted absorption spectra, and stronger intermolecular interactions. The HOMO and lowest unoccupied molecular orbital (LUMO) in PBDTBzT-DTffBT are decreased by 0.11 and 0.13 eV, respectively, which should be attributed to the contribution of the electron-withdrawing group benzene. Polymer solar cells (PSCs) based on PBDTBzT-DTffBT and [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM) exhibit a maximum power conversion efficiency (PCE) of 7.30% with a large open-circuit voltage of 0.90 V under AM 1.5G illumination (100 mW/cm2). The PCE is 36% higher than that of the PSCs derived from PBDTT-DTffBT. These findings provide a new approach to design high-performance conjugated polymers for efficient solution-processed PSCs.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. COA of Formula: C8H5BrS, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 4923-87-9, in my other articles.

New synthesis of aryl and heteroaryl N-acylureas via microwave-assisted palladium-catalysed carbonylation

A new, practical synthesis of aryl and heteroaryl N-acylureas has been developed via palladium-catalysed carbonylation of aryl or heteroaryl halides in the presence of urea nucleophiles. A range of reactions illustrating the wide scope of this reaction was carried out under microwave irradiation, using either carbon monoxide gas in a vessel equipped with a gas inlet adapter, or molybdenum hexacarbonyl as the carbon monoxide source in standard microwave vials. The reactions proceeded in good to excellent yields. To illustrate the usefulness of this method a one-step synthesis of the important insecticide diflubenzuron is reported.
