The reactions of trimethylsilylazide (TMSA) with various aldehydes were found to be versatile procedures for the synthesis of gem- and 1,3-diazides, tetrazoles, and nitriles, whose formation was varied by controlling the quantities of TMSA, catalyst, and the reaction conditions.

the first time, a sensitive azidocarbenium ionintermediate has been trapped with various nucleophiles to provide azides in excellent chemoselectivity. This provides a novel approach for the chemoselective synthesis of primary and secondary benzyl azides from aldehydes in a one-pot reaction. Enantioselective nucleophilic addition to the azidocarbenium ion has also been initiated.

Triflic acid (TfOH) is used as a catalyst for the conversion of aldehydes into gem‐diazides by using trimethylsilyl azide. In a one‐pot synthesis method, the obtained diazide is treated with an N‐heterocyclic carbene or triphenylphosphane to obtain a gem‐bis(triazabutadiene) compound or a cationic N,N′‐bis(triphenylphosphane) adduct, respectively.
