A variety of symmetrical 1, l-bis (heteroary1) alkanes are prepared in excellent yields from the reaction of N-(a-benzotriazolylalky1) carbamate 2 (itself easily available from the condensation of benzotriazole, an aldehyde, and an alkyl carbamate) with an excess of 2- methylthiophene or 2-methylfuran. When methyl N-(a-benzotriazolylalkyl) carbamate 2a is treated with 1 equiv of a heterocycle, the benzo-triazolylalkyl-substituted heterocycle is ...
