Computed Properties of C4H2Br2S The article mentions the following:
A bithiophene-alkyne-based compound was synthesized and 1st used as a ligand for the selective hydrosilylation of allenes with primary and secondary phenylsilanes. It shows high selectivity towards the production of branched allylsilanes with a wide range of allenes. It is worth mentioning that the catalytic loading of the Pd can be reduced to 500 ppm. This work opens a new front of using bidentate thiophene ligand as a reaction promoter in transition-metal-catalyzed organic reaction. The experimental process involved the reaction of 2,5-Dibromothiophene(cas: 3141-27-3Computed Properties of C4H2Br2S)
2,5-Dibromothiophene(cas: 3141-27-3) , is mainly used as pharmaceutical intermediate and synthesis intermediate. 2,5-Dibromothiophene may be used in the preparation of soluble α,ω-diformyl-a-oligothiophenes.Computed Properties of C4H2Br2S
