Synthesis of isocyanates from carboxylic acids using diphenylphosphoryl azide and 1,8-bis(dimethylamino)naphthalene

Article abstract of DOI:10.1080/00397919308009785

A simple phosgene-free method for the synthesis of high-purity isocyanates from carboxylic acids was developed using diphenylphosphoryl azide and 1,8-bis(dimethylamino)naphthalene. Yields for evaluated monoisocyanates ranged from 60.0% to 81.5%.
