The 2-phosphinophosphinine 2-PPh2-3-Me-6-SiMe3-PC5H2 (2) has been prepared and was shown to act as a κ2-chelating ligand in cis-[RuCl2(2)2] (4). Complex 4 was a competent precatalyst for the room temperature transfer hydrogenation of acetophenone (0.1 mol% 4 and 0.5 mol% KOtBu) and the conversion of methanol/ethanol mixtures to the advanced biofuel isobutanol in 50% yield and 96% selectivity.
