Methylplatinum(II) complexes containing 2-(diphenylphosphino)pyridine (Ph2Ppy). Crystal and molecular structure of [PtMe(η2-Ph2Ppy)(Ph2Ppy)][BPh4]

2-Pyridyl substituents enhance the activity of palladium–phospha-adamantane catalysts for the methoxycarbonylation of phenylacetylene

“…The signal at −48.1 ppm is assigned to the P,N-chelate since its high field shift is characteristic of a 4-membered chelate. 16 The lower value of 1 J P,Pt for the chelate-P is consistent with the ring strain being relieved by lengthened Pt-P bonds; the crystal structure of the Pd analogue 5[BF 4 ] (see below) supports this inference.…”

Pincer Complexes Based on Phosphinoaminopyridines: Synthesis, Structural Characterization and Catalytic Applications

“…The small bite angle of the ligand causes noticeable distortions from ideal square planar geometry. [BF 4 ] was prepared by the addition of a halide abstractor to cis-[PtClMe{Ph 2 Ppy-P} 2 ] in solution and the product has been crystallographically characterised [22]. There is a good 31 P{ 1 H} NMR evidence for the structural assignment of 15.…”

Synthesis and characterization of ruthenium(II) complexes based on diphenyl-2-pyridylphosphine and their applications in transfer hydrogenation of ketones

“…Ru(II) complexes are generally employed as the most useful catalysts for such reactions [3,[28][29][30][31][32][33]. To develop and explore hydrogen transfer catalysts in the present study, we choose PPh 2 Py as a versatile ligand which may bind the metal center in a monodentate, chelating or bridging mode depending upon requirements at the reaction center [34][35][36][37][38][39]. In its chelating coordination mode it forms four membered rings which are strained, relatively unstable and plays a vital role in catalysis [40][41][42][43][44].…”
