The first Diels–Alder reaction of a 9,10-bis(1,3-dithiol-2-ylidene)-9,10-dihydroanthracene derivative: synthesis and crystal structure of a novel donor–π–anthraquinone diad
Abstract
An exocyclic diene derivative of 9,10-bis(1,3-dithiol-2-ylidene)-9,10-dihydroanthracene undergoes Diels–Alder reaction with naphthoquinone to provide the D–π–A diad 10.
