Synthesis and Characterization of Phosphinecarboxamide and Phosphinecarbothioamide, and Their Complexation with Palladium(II) Complex.

Reactions of isocyanates/isothiocyanates with primary and secondary phosphines without solvent at room temperature afforded phosphinecarboxamide/phosphinecarbothioamide, respectively, in excellent yields. Furthermore, palladium complex Pd(COD)Cl was allowed to react with PhPC(O)NHPh () to afford [Pd{PhPC(O)NHPh-κ}Cl] (). On the other hand, the reaction of Pd(COD)Cl with 1 eq.

Convenient synthesis of phosphinecarboxamide and phosphinecarbothioamide by hydrophosphination of isocyanates and isothiocyanates.

Reactions of isocyanates with primary and secondary phosphines without solvent at room temperature afforded the corresponding phosphinecarboxamide (RN(H)COPR'2) in excellent yields. This reaction system is applicable for isothiocyanates. The compounds newly obtained were fully characterized using multielement NMR spectroscopy.
