The behavior of certain diarylchloroethenes with potassium amide in liquid ammonia has been reported previously. A rapid reaction occurs and the ethenes are changed with the loss of hydrochloric acid to tolanes. Thus 1, 1-di-p-tolyl-2-chloroethene forms p. p'-dimethyltolane. A series of such para substituted compounds was studied and as anticipated only symmetrical tolanes were obtained.
