Abstract

A dithienylethene synthon, 3,4-bis-(5-iodo-2-methylthien-3-yl)-2,5- dihydrothiophene, was prepared and used as a starting material for the preparation of several photochromic dithienylethene derivatives via Suzuki cross-coupling reactions. The dithienylethene synthon was stable once stored in the dark at room temperature.
