Electrochemically Enabled Selenium Catalytic Synthesis of 2,1-Benzoxazoles fromo-Nitrophenylacetylenes

The study reported an electrochemically mediated method for the preparation of 2,1-benzoxazoles fromo-nitrophenylacetylenes. Different from the traditional electrochemical reduction of nitro to nitroso, the nitro group directly underwent a cyclization rea

Synthesis of alkynes under dry reaction conditions

An easy synthetic method was developed under dry reaction conditions for the preparation of terminal alkynes from 1,1-dibromoalkenes and in the presence of succinimide which acts as a nucleophile and proton donor. It was demonstrated with the synthesis of a broad spectrum of terminal alkynes and extended to synthesize internal alkynes under tandem reaction conditions.
