Photochromic terarylene derivative 4 which has a sulfone group at the upper benzothiophene ring is readily synthesized using Suzuki coupling reaction. It exhibits good photochromic properties.

The synthesis and utilization of a class of 2,1-borazaronaphthyltrifluoroborate reagents that provide a general solution to the challenge of N-functionalization of the 2,1-borazaronaphthalene core is described. By adorning the nitrogen of this core with a trifluoroboratomethyl unit, a suite of odd-electron processes can be executed, installing motifs that would otherwise be inaccessible using a two-electron approach. In addition, this process enables rapid annulation, furnishing a heretofore unknown polycyclic B-N species.

The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. In a article, 6287-82-7, molcular formula is C8H4Br2S, introducing its new discovery.

The following work presents three general approaches allowing, for the first time, the synthesis of 5,10-diheterotruxene derivatives containing two identical heteroatoms, namely, oxygen OOC, nitrogen NNC, or sulfur SSC. Two of described pathways involve the photocyclization of the corresponding triene 2 as a key step leading to a heptacyclic aromatic system. The third approach is based on the acidic condensation between ninhydrin 14 and benzo[b]heteroole 15. Typical functionalizations of the 5,10-diheterotruxene core have also been presented. In addition, the article discusses the advantages and limitations of the three suggested paths for receiving specific 5,10-diheterotruxene derivatives because the universal method suitable for obtaining molecules with any type of heteroatoms is not known so far.

Controlling the internal motions of molecules by outside stimuli is a decisive task for the generation of responsive and complex molecular behavior and functionality. Light-induced structural changes of photoswitches are of special high interest due to the ease of signal application and high repeatability. Typically photoswitches use one reaction coordinate in their switching process and change between two more or less-defined states. Here we report on new twisted hemithioindigo photoswitches enabling two different reaction coordinates to be used for the switching process. Depending on the polarity of the solvent, either complete single bond (in DMSO) or double bond (in cyclohexane) rotation can be induced by visible light. This mutually independent switching establishes an unprecedented two-dimensional control of intramolecular rotations in this class of photoswitches. The mechanistic explanation involves formation of highly polar twisted intramolecular charge-transfer species in the excited state and is based on a large body of experimental quantifications, most notably ultrafast spectroscopy and quantum yield measurements in solvents of different polarity. The concept of pre-twisting in the ground state to open new, independent reaction coordinates in the excited state should be transferable to other photoswitching systems.

Use of hazardous reagents is common in most of the reported synthesis of molecules of various interests. Hazardous reagents at a manufacturing scale pose a great challenge in terms of handling, operation and workups. These reagents are unsafe and found to have proven toxicity (in the majority of the cases). If not avoided, these reagents will defy the purpose of Green Chemistry and sustainability in organic synthesis. In this chapter, the synthesis of raloxifene, [6-Hydroxy-2-(4-hydroxyphenyl)-1-benzothiophen-3-yl]{4-[2-(piperidin-1-yl)eth-oxy] phenyl}methanone hydrochloride 1, an estrogen agonist/antagonist commonly considered as a selective estrogen receptor modulator (SERM), will be discussed considering the evolving trends of switching the usage of hazardous to less hazardous reagents. Raloxifene impedes the re-sorption of bone by reducing the biochemical markers of bone turnover in the premenopausal women thereby helping in the management of osteoporasis. Raloxifene hydrochloride also lowers the chances of developing a certain type of breast cancer (invasive breast cancer) in post-menopausal women.
