Among several useful transformations of the readily available N-arylimino-1
,2,3-dithiazoles 1 is their rapid conversion by lithium aluminum hydride in
to the rearranged N-aryldithiooxamides, ArNHCSCSNH2, thus providing a two s
tep synthesis of these unsymmetrical rubeanic acid derivatives from ArNH2 (
9 examples).
