摘要

It has been shown that the reaction of dithiooxamide (rubeanic acid) with aromatic aldehydes is a condensation process involving concurrent loss of two hydrogen atoms. In one instance it was possible to isolate a labile intermediate condensation product that had not undergone dehydrogenation. The tmo aryl groups in the typical reaction products were shown to be structurally equivalent and the heterocyclic system to be remarkably stable ...
