Abstract

The violet title compound (3) has been synthesized from the bis-thioacetal (4) in two steps, the last of which involves a based catalyzed vinylogous Pummerer dehydration of a sulfoxide. Some chemical and physical properties of (3), which may be viewed as a “push-pull” stabilized quinodimethane, are described.
