Metal-free carboxamidation of P(O)H compounds with in situ formed isocyanates from dioxazolones: a convenient access to carbamoylphosphine oxides

A facile and metal-free method for synthesizing structurally diverse carbamoylphosphine oxides from dioxazolones and P(O)H compounds was developed. In these transformations, isocyanates were formed in situ by the decarboxylation and...
