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 13C spectra of nine novel and fifteen known derivatives YC(:X)Z with X = O or S are reported and compared with literature data. Two linear relationships between 13CO and 13CS are established depending on whether or not Y or Z is linked through an O atom to the CX group. General equations for 13CO and 13CS in terms of the attached groups are also deduced. The 13C chemical shifts of n-butyl and n-octyl groups attached to the heteroatoms in this series of compounds are recorded and discussed.
