Functionalized Heterocumulenes: Synthesis and Applications of Phenylthiomethyl, Methylthiomethyl, Bis[phenylthio]methyl Isocyanates and Phenylthio-acetyl and Methylthio-acetyl Isothiocyanates
A series of N-substituted aryl and alkylcarbamates (RNHCOOR'; R: aryl, alkyl; R': aryl, alkyl) was prepared and screened for inhibitory activity toward the germination of oat seeds. The activity of each compound was compared with that of chlorpropham (isopropyl 3-chlorocarbanilate). Some of the synthetic carbamates possessing the N-(phenylthio)methyl group, PhSCH2NHCOOR', showed inhibitory activity

: Bonds between arylheteroatom moieties and α-carbons of carboxylic acids are efficiently cleft by azide transfer and subsequent Curtiusrearrangement. The scope of the one-pot protocol covers differently substituted carboxylic acids and heteroatoms like O, S, Se, and N.
