S3•–-mediated [1 + 2 + 2] and [1 + 3 + 1] cycloaddition reactions of aromatic alkynes to give tetraphenylthiophene and 2-benzylidenetetrahydrothiophene derivatives via two C–S bond formations are developed. These two protocols provide new, simple, and straightforward strategies to construct tetraphenylthiophene and 2-benzylidenetetrahydrothiophene derivatives under transition-metal-free conditions

Silver‐catalyzedcoupling of twoCHgroups to form 1,4‐diketones have been developed for the first time. The resultant ketones then undergo cyclization to synthesize tetrasubstitutedfurans, thiophenes, and pyrroles from benzyl ketone derivatives in a one‐pot reaction process. This highly‐efficient synthetic method, which utilizes air as the terminal oxidant and readily accessible starting materials
