Abstract

Synthesis and Characterization of Fused Mesoionic 1,3,4-Oxadiazolium-2-thiolates from N-Amino-N,N'-dihydrodiazinediones.-Novel fused mesoionic 1,3,4-oxadiazolium-2-thiolates are prepared from the reaction of N-amino-N,N'-dihydrodiazinediones (I) and carbon disulfide. Studies of their reactivity show that they have weaker stability than monocyclic mesoionic 1,3,4-oxadiazolium-2-thiolates. -(JEON, D.
