Treatment of Tp′Rh(PMe3)Cl2 and Tp′Rh(CNCH2CMe3)Cl2 with Cp2ZrH2 produces Tp′Rh(PMe3)H2 and Tp′Rh(CNCH2CMe3)H2, respectively, in excellent yield. Photolysis of benzene solutions of each dihydride complex generates hydrogen and the fragment [Tp′Rh(L)] which inserts into the solvent C–H bond. The phosphine dihydride has also been shown to be a catalyst for the hydrogenation of biphenylene, showing a capability to cleave C–C bonds. Reductive elimination of benzene from Tp′Rh(PMe3)PhH is nearly 250 times slower than from Cp*Rh(PMe3)PhH.
