Abstract Miscellaneous phosphohrylated carbamates, ureas and thioureas of potential value as flame retardants for cotton have been synthesized from a key intermediate, tris (aminomethyl) phosphine oxide (1), whose synthesis we recently described. Reactions were carried out between 1 and representative chloroformates, isocyanates, thiocyanates and ureas, and with carbonyl sulfide and carbon disulfide. An improved procedure was ...
