Abstract:
A 3-methoxythiophene-based indophenine reaction with N-(2-hexyldecyl)isatin in the presence of concentrated sulfuric acid produces an indophenine cis-trans isomeric dynamic equilibrium system, which is dominated by the (Z,E,Z) configuration with a trace of the (Z,Z,Z) configuration.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
