Synthesis of (E)-2,5-disubstituted 1,3,4-thiadiazolyl-2,3-diphenylpropenones from alkenylidene-hydrazinecarbothioamides
摘要:
Conjugated alkenylidene-hydrazinecarbothioamides react in high yield with 2,3-diphenylcyclopropenone to give a series of (E)-2,5-disubstituted 1,3,4-thiadiazolyl-2,3-diphenylpropenones. (C) 2012 Elsevier Ltd. All rights reserved.
