Abstract
Regioselective methods to access alkylated tetrazoles still remain a challenging goal. Herein, we describe a novel regioselective protocol for N2-arylation of tetrazoles with diazo compounds using inexpensive Al(OTf)3. This reaction could be conducted under mild conditions to access a diverse array of alkylated tetrazoles with 2-substituted tetrazoles as the major products, demonstrating a comprehensive range of substrate compatibility and excellent functional group compatibility. Mechanistic studies revealed a carbene-free process in this reaction procedure. Furthermore, the scale-up reaction and transformations of the N2-arylation of tetrazole products demonstrated the potential of this strategy.

Abstract
An efficient route to construct 2,5-disubstituted tetrazole hemiaminal silyl ethers via one-pot three-component hemiaminal silylation of 5-substituted tetrazoles, aldehydes, and silyl triflates was developed. Diverse 2,5-disubstituted tetrazole hemiaminal silyl ethers were obtained with 37 : 63->99 : 1 regioisomeric ratios. The regioselectivities of this reaction were significantly affected by steric hindrance and the conjugation effects of substitutions on the 5-position of tetrazoles.
