DMF and DMSO catalyse the reaction of butanol with PhNCO but inhibit that with aliphatic isocyanates, due to formation of an active 1 : 1 charge transfer complex with the aromatic isocyanate.

## Abstract The reaction between isocyanates and carboxylic acids is known to lead to amides. We have studied the mechanism of catalysis of this reaction by phospholene oxides. The reaction between phenyl isocyanates and benzoic acid was monitored under various conditions using High‐Pressure Liqui
