The ruthenium-p-cymene complexes [p-cymene)Ru(1,2,3,4-Me 4-NUPHOS)Cl][SbF6] and [(p-cymene)Ru(1,4-Et 2-2,3-cyclo-C6H8-NUPHO S)Cl][SbF6] were prepared by reaction of [(p-cymene)RuCl2]2 with the corresponding NUPHOS diphosphine in the presence of NaSbF6. The crystal structures of these complexes were determined by single-crystal X-ray crystallography. The highly regio- and stereoselective addition of benzoic acid to phenylacetylene using catalysts based on NUPHOS was studied. The higher cis-to-trans ratios for anti-Markovnikov addition of benzoic acid to terminal alkynes with NUPHOS-based catalysts compared with their biaryl-based counterparts.
