Abstract
Abstract 1,8-Diazabicyclo[5.4.0]undec-7-ene, DBU, reacts with (OC)4Ru(μ-PPh2)Co(CO)3 (1) at room temperature to give an intermediate 2, which on protonation in the presence of Co regenerates 1 and on protonation in the presence of PMe3, gives the monosubstituted product (OC)3(L)Ru(μ-PPh2)Co(CO)3 (3 L = PMe3). DBU promotes the selective formation of 4(L = PPh2Me) or 5 (L = Ph2PCh2C(Me)CH2) in one-step from 1, Ph2PH, and methyl iodide or methallyl chloride, respectively.
