A variety of 2-allylated-5-substituted tetrazoles were prepared in excellent yields through the reaction of alkyland arylidenemalononitriles, allyl acetates and trimethylsilyl azide in the presence of a palladium catalyst.

β¦ Synopsis
Palladium catalyzed reaction of ally1 acetates with azide ion gives ally1 azides, which are readily converted into the corresponding primary allylamines upon treatment with PPhS/NaOH. The catalytic transformation of allylic substrates via n-ally1 palladium complexes is now well d0cumented.l

Ally1 diethyl phosphates (\_1) can be easily substituted with malonates and amines in the presence of palladium(O) catalyst. Synthetic utility of the reaction is demonstrated by the sequential amination-amination and alkylation-amination of (Z)-4-acetoxybut-2-enyl diethyl phosphate Cl,b) with high r
