A ruthenium cis-dihydride with 2-phosphinophosphinine ligands catalyses the acceptorless dehydrogenation of benzyl alcohol

The first ruthenium dihydride complex featuring a phosphinine ligand cis-[Ru(H)(2)(2-PPh2-3-Me-6-SiMe3-PC5H2)(2)] was synthesised exclusively as the cis-isomer. When formed in situ from the reaction of cis-[Ru(Cl)(2)(2-PPh2-3-Me-6-SiMe3-PC5H2)(2)] with two equivalents of Na[BHEt3], as demonstrated b...

Zusammenfassung:The first ruthenium dihydride complex featuring a phosphinine ligand cis-[Ru(H)(2)(2-PPh2-3-Me-6-SiMe3-PC5H2)(2)] was synthesised exclusively as the cis-isomer. When formed in situ from the reaction of cis-[Ru(Cl)(2)(2-PPh2-3-Me-6-SiMe3-PC5H2)(2)] with two equivalents of Na[BHEt3], as demonstrated by P-31 and H-1 NMR spectroscopy, the catalysed acceptorless dehydrogenation of benzyl alcohol was observed leading to benzyl benzoate in up to 70% yield.
