Synthesis of some N1-phenyl-N3-[2-aryl/aryloxymethyl-1,3,4-oxa(thia)diazol-2-yl]sulphonyl ureas as potential pesticides
Srivastava,Nizamuddin
, p. 161 - 166 (2007/10/03)
N1-Phenyl-N3-aryl/aryloxymethyl[1,3,4-oxa(thia)diazol-2-yl]sulphonyl ureas (4 and 7) were conveniently prepared from 2-aryl/aryloxymethyl-1,3,4-oxa(thia)diazol-2-sulphonamide (3 and 6) and phenyl isothiocyanate. Sulphonamides were sy
