Synthesis and properties of tetrazolium-N-phenacylides. Part 2
摘要:
Various 1 -alkyl-5-methyl-1H-tetrazolium-4-phenacylides 3 (homologues of C) have been prepared, acylated and (thio)carbamoylated. The unstable ylide C has been acylated in situ.

In the presence of Lewis acid such as SnCl2, the reactions of trimethylsilylazide with ketones readily gave 1:1- or 1:2-adduct, which reacted with Lewis acid to afford tetrazole.

Golden duality: Tetrazoles are formed by the reaction of alkynes with TMSN3 (TMS=trimethylsilyl) in the presence of iPrOH and the gold(I) catalyst [JohnPhosAu(MeCN)]SbF6. In this transformation gold plays a dual role, first activating the alkyne and then generating a Brønsted acid in situ.
