A simple and efficient solvent-free preparation of primary carbamates,S-thiocarbamates and ureas from alcohols, phenols, thiols and amines in the presence of 4-dodecylbenzenesulfonic acid, as a cheap and green Brønsted acid, has been described.

The kinetics of the aminolysis of aryl thiocarbamates [ATC: H2NC(=O)SC6H4Z] with benzylamines (XC6H4CH2NH2) in acetonitrile at 10.0 degrees C have been studied. The rate order with variation of the non-leaving amino group, RNH, in RNHC(=O)SC6H4Z is NH2 < PhNH < EtNH indicating that the polar (sigma*) and steric (E(s)) effects of the RNH group are insignificant, and the strength of push to expel the
