摘要

A series of substituted p-terphenyls and 11, 12-dihydroindeno [2, 1-a] fluorene were successfully synthesized by one-pot benzannulation of Diels–Alder reaction with 1, 2- dichloroethene as an acetylene equivalent dienophile. Two chlorine atoms could be good leaving groups to easily undergo subsequent elimination reactions of Diels–Alder products at a high temperature.
