Organo-phosphorus compounds S 0080Rhodium-Catalyzed Synthesis of 1-Alkynylphosphine Oxides from 1-Alkynes and Tetraphenylbiphosphine. -A Rh-catalyzed C-H and P-P bond metathesis reaction between terminal alkynes and biphosphine (II) gives 1-alkynyl phosphine oxides after oxidative treatment. Optimization of the conditions reveals that DMNB efficiently promotes the metathesis step. -(ARISAWA, M.; ONODA, M.; HORI, C.; YAMAGUCHI*, M.; Tetrahedron Lett. 47 (2006) 29, 5211-5213; Dep. Org.
