Reactions of Phosphonic and Phosphoric Dichlorides with Sodium Cyanate as a General Synthesis Method of Phosphoryldiisocyanates

摘要

Phosphoryldiisocyanates XP(O)(NCO)2 are promising precursors for synthesis of various classes of organophosphorous compounds: phosphorylated ureas, urethans, carbodiimides, heterocycles, etc, which are in turn of great interest as organophosphorus extractants, complex-ing agents, sorbates, polymers, biologically active compounds and other practically useful substances.
