Abstract:

Chalcogenoacetylenes belongs to an important class of compounds on organic synthesis. The literature shows different methodologies to synthesize these compounds using different metals such as copper, indium or magnesium. On the other hand, there are wide lacks of information around bismuth chemistry, especially applied to coupling reaction to afford chalcogenoacetylenes, even its salts presenting low toxicity and low cost when compared with others metals. Join together the advantages from bismuth and its salts with one pot or multicomponent reactions we fulfill important topics at green chemistry such as atom economy, low toxicity, low cost and short pathways synthesis. Thus, in this work we developed an one pot methodology using bismuth and its salts to synthesize chalcogenoacetylenes compounds.
