Reactions of 1,4-bis(tetrazole)benzenes: formation of long chain alkyl halides

Reactions of 1,4-bis[2-(tributylstannyl)tetrazol-5-yl]benzene with α,ω-dibromoalkanes led to the formation of several alkyl halide derivatives, substituted variously at N1 or N2 on the tetrazole ring. The X-ray crystal structures of a number of derivatives are discussed.
