摘要：

7-Phenyl-8-(ethoxycarbonyl)-7,8-dicyanoquinodimethane (1), a new unsymmetrical electrophilic quinodimethane, was synthesized. The first reduction potential of 1 is -0.33 V by cyclic voltammetry. Compound 1 can be homopolymerized with an anionic catalyst. It spontaneously copolymerized free radically with p-methoxystyrene, p-methylstyrene, and styrene at 60 °C, and alternating copolymers with high molecular weight were obtained. The propagation mode of the copolymerization for the 1-MeOSt system is discussed. N-Vinylcarbazole (NVCz) with 1 under the same conditions formed only NVCz homopolymer by spontaneous polymerization. © 1990, American Chemical Society. All rights reserved.
