Abstract :
Among some bismuth catalysts, bismuth trifluoromethanesulfonate showed excellent catalytical properties in the transcarbamoylation reaction between a N-alkyl O-alkyl carbamate and a primary alcohol. It was found more active than classical organotin catalysts. Moreover it was also more selective as no alkyl isocyanate was detected during the transcarbamoylation.
