The first ruthenium dihydride complex featuring a phosphinine ligand -[Ru(H)(2-PPh-3-Me-6-SiMe-PCH)] was synthesised exclusively as the -isomer. When formed from the reaction of -[Ru(Cl)(2-PPh-3-Me-6-SiMe-PCH)] with two equivalents of Na[BHEt], as demonstrated by P and H NMR spectroscopy, the catalysed acceptorless dehydrogenation of benzyl alcohol was observed leading to benzyl benzoate in up to 70% yield.
