Cu(I)-mediated cycloaddition reaction of zirconacyclopentadienes with fumaronitrile and application for synthesis of monocyano-substituted pentacenes
摘要:
Cu(I) -mediated reactions of zirconacyclopentadienes with fumaronitrile afforded the corresponding dicyanocyclohexadiene and benzonitrile derivatives in good yields. These products were selectively prepared by controlling the reaction temperature. Furthermore, the reaction was applicable for monocyano-substituted pentacene derivatives.
