2-(2'-Pyridyl)-4,6-diphenylphosphinine versus 2-(2'-pyridyl)-4,6- diphenylpyridine: an evaluation of their coordination chemistry towards Rh(I)

摘要

The coordination chemistry of the bidentate P,N hybrid ligand 2-(2'-pyridyl)-4,6-diphenylphosphinine towards Rh(I) has been investigated and compared to the structurally analogous 2,2'-bipyridine derivative. Considerable differences in the molecular structures of the mononuclear [Rh(cod)L2lBF4 complexes were observed and attributed to the different steric and electronic properties of functionalized phosphinines compared to pyridines.
