Catalytic isomerization of allylic alcs. in ethanol as a green solvent was achieved by using air and moisture stable cobalt (II) complexes in the absence of any additives. Under mild conditions, the cobalt PNP pincer complex substituted with Ph groups on the phosphorus atoms appeared to be the most active. High rates were obtained at 120°, even though the addition of one equivalent of base increases the speed of the reaction drastically. Although some evidence was obtained supporting a dehydrogenation-hydrogenation mechanism, it was proved that this is not the major mechanism. Instead, the cobalt hydride complex formed by dehydrogenation of ethanol was capable of double-bond isomerization through alkene insertion-elimination.

SDS of cas: 1086138-36-4. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Bis(2-(Di(adamantan-1-yl)phosphino)ethyl)amine, is researched, Molecular C44H69NP2, CAS is 1086138-36-4, about Catalytic Hydrogenation of Cyclic Carbonates: A Practical Approach from CO2 and Epoxides to Methanol and Diols. Author is Han, Zhaobin; Rong, Liangce; Wu, Jiang; Zhang, Lei; Wang, Zheng; Ding, Kuiling.

A highly efficient catalytic hydrogenation of cyclic carbonates was developed for the preparation of methanol with the cogeneration of the corresponding diols by using (PNP) Ru”” pincer complexes as the catalysts under relatively mild conditions. This process has provided a facile approach for the simultaneous production of two important bulk chems., methanol and EG, from ethylene carbonate, which is industrially available by reacting ethylene oxide with CO2. The coupling of the present catalytic system with the process of ethylene carbonate production in the omega process is expected to establish a new bridge from CO2 and ethylene oxide to methanol and EG. Apart from the clean production of diol, a big bonus of the present protocol is the efficient chem. utilization of CO2, which represents a distinct advantage in terms of sustainability over the omega process, which gives back CO2. Moreover, this catalytic system has also provided a potential process for the utilization of waste poly(propylene carbonate) as a resource to afford 1,2-propylene diol and methanol through hydrogenative depolymerization, and a convenient method for the preparation of deuterated methanol from CO2 and D2. A possible catalytic mechanism is proposed, in which the NH moiety of the ligand is demonstrated to be critically important in facilitating the reduction of the carbonate C=O bond through secondary coordination sphere interactions with substrates.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Bis(2-(Di(adamantan-1-yl)phosphino)ethyl)amine(SMILESS: P(CCNCCP(C12CC3CC(C2)CC(C3)C1)C45CC6CC(C5)CC(C6)C4)(C78CC9CC(C8)CC(C9)C7)C%10%11CC%12CC(C%11)CC(C%12)C%10,cas:1086138-36-4) is researched.Application In Synthesis of H-Trp-OMe.HCl. The article 《Erbium-Catalyzed Regioselective Isomerization-Cobalt-Catalyzed Transfer Hydrogenation Sequence for the Synthesis of Anti-Markovnikov Alcohols from Epoxides under Mild Conditions》 in relation to this compound, is published in ACS Catalysis. Let’s take a look at the latest research on this compound (cas:1086138-36-4).

Herein, we report an efficient isomerization-transfer hydrogenation reaction sequence based on a cobalt pincer catalyst (1 mol%), which allows the synthesis of a series of anti-Markovnikov alcs. from terminal and internal epoxides under mild reaction conditions (≤55°, 8 h) at low catalyst loading. The reaction proceeds by Lewis acid (3 mol % Er(OTf)3)-catalyzed epoxide isomerization and subsequent cobalt-catalyzed transfer hydrogenation using ammonia borane as the hydrogen source. The general applicability of this methodol. is highlighted by the synthesis of 43 alcs. from epoxides. A variety of terminal (23 examples) and 1,2-disubstituted internal epoxides (14 examples) bearing different functional groups are converted to the desired anti-Markovnikov alcs. in excellent selectivity and yields of up to 98%. For selected examples, it is shown that the reaction can be performed on a preparative scale up to 50 mmol. Notably, the isomerization step proceeds via the most stable carbocation. Thus, the regiochem. is controlled by stereoelectronic effects. As a result, in some cases, rearrangement of the carbon framework is observed when tri- and tetra-substituted epoxides (6 examples) are converted. A variety of functional groups are tolerated under the reaction conditions even though aldehydes and ketones are also reduced to the resp. alcs. under the reaction conditions. Mechanistic studies and control experiments were used to investigate the role of the Lewis acid in the reaction. Besides acting as the catalyst for the epoxide isomerization, the Lewis acid was found to facilitate the dehydrogenation of the hydrogen donor, which enhances the rate of the transfer hydrogenation step. These experiments addnl. indicate the direct transfer of hydrogen from the amine borane in the reduction step.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds.
