摘要：
Sulfur heterocyclization and 1,3-migration of silicon have been realized in the reactions of a range of 1,3-diynes with sodium triisopropylsilanethiolate in N,N-dimethylformamide. These provided 40-72% yields of 2,5-disubstituted 3-(triisopropylsilyl)thiophenes and up to 50% yield of 2,5-disubstituted thiophenes.
