An efficient palladium catalyzed cross coupling of tributyl(vinyl)stannane with dialkoxy and dialkyl substituted 1,4-dihalobenzenes is described. This single-step coupling provides an efficient synthesis of functionalized 2,5-divinylbenzenes, which are useful precursors of 1,4-phenylenevinylene copolymers.

A simple and inexpensive method for preparing the previously unknown 2,5-di-n-alkylterephthalic acids 5a-d in high yields is presented. The length of the alkyl chains can be varied easily (n = 6, 8, 12, 16).
