Phosphaallyl complexes of Ru(ii) derived from dicyclohexylvinylphosphine (DCVP)
Abstract
The complexes [(η5-RC5H4)Ru(CH3CN)3]PF6
(R = H, CH3) react with DCVP (DCVP = Cy2PCHCH2) at room temperature to produce the phosphaallyl complexes [(η5-C5H5)Ru(η1-DCVP)(η3-DCVP)]PF6
(1) and [(η5-MeC5H4)Ru(η1-DCVP)(η3-DCVP)]PF6
(2). Both compounds react with a variety of two-
