An easy and efficient one-step procedure for the preparation of alkyl and aryl alkylcarbamates from S-methyl N-alkylthiocarbamates

A general, one-step procedure for the synthesis of alkyl and aryl alkylcarbamates, by the direct reaction of S-methyl N-alkylthiocarbamates with alcohols or phenols in toluene at reflux in the presence of triethylamine, is reported. All the target products were obtained in high yield (15 examples, average yield 94%) and very high purity (>99.2%). The recovery of a co-product of industrial interest, methanethiol, in an amount of one mole for each mole of thiocarbamate, with complete exploitation of the reagent, should also be noted.

One-pot, three-step preparation of alkyl and aryl alkylcarbamates from S-methyl N-alkylthiocarbamates

A general procedure for the synthesis of alkyl and aryl alkylcarbamates starting from the corresponding 5-methyl N-alkylthiocarbamates is described. This procedure consists of three steps that are carried out in a one-pot fashion, without isolating the intermediate N-alkylcarbamoyl chlorides or alkyl isocyanates. All the target products were obtained in high yields (16 examples, average yield 91%). To be noted is the recovery of a co-product of industrial interest, dimethyl disulfide, in a half mole amount for each mole of thiocarbamate, with complete exploitation of the reagent. The alkyl isocyanates, if required, can also be isolated in high yields. Georg Thieme Verlag Stuttgart.
