Selenium analogues of 2-(thiopyran-4-ylidene)-1,3-dithiole as novel unsymmetrical electron donors
Abstract
The selenium analogues of 2-(thiopyran-4-ylidene)-1,3-dithiole and its 4,5-bis(methylthio) and 4,5-(ethylenedithio) derivatives have been prepared as a new series of unsymmetrical electron donors; some of their complexes with 7,7,8,8-tetracyanoquinodimethane are electrically highly conductive.
