Unexpected formation of amidino-thiadiazolines by reaction of a chlorodiazabutadiene with thioureas
Abstract
Treatment of Ph(Cl)C : NN : CHPh with thioureas affords hydrochlorides which, on basification, liberate novel amidines in which the amidine function is attached to the 4-position of Δ2-1,3,4-thiadiazolines.
