Abstract
Attempts were made to prepare novel 7-alkoxycarbonyl-7,8,8-tricyanoqui nodimethanes (ethoxy(5a), isopropoxy(5b), and tert-butoxy(5c)), 7,7-bi s(alkoxycarbonyl)-8,8-dicyanoquinodimethanes (ethoxy(6a), isopropoxy(6 b), and tert-butoxy(6c)), and dene)-4-(dicyanomethylene)-2,5-cyclohexa diene(6d). 5c and 6d were obtained as yellow and orange needles, respe ctively, but 5a, 5b and 6a-c could not he isolated as crystals. Homopo lymerizations of 5c and 6d and their copolymerizations with styrene we re studied. (C) 1997 Elsevier Science Ltd.
