Abstract
Bis(2-hydroxy-1-naphthyl)methane reacts with chlorodiphenylphosphine to afford the bis(phosphinite), Ph2P{(OC10H6)(μ-CH2)(C10H6O)}PPh2 (1 ) in good yield. The bis(phosphinite) 1 reacts with elemental sulfur or selenium to give the corresponding disulfide or diselenide; the structure of the selenium derivative, Ph2P(Se){(OC10H6)(μ-CH2)(C10H6O)}P(Se)Ph2 (3 ) is confirmed by X-ray crystal structure analysis. Treatment of the ligand 1 with platinum metal derivatives results in the formation of ten-membered chelate complexes with the ligand showing an η2 -mode of coordination. The elucidation of the structures of the products is based on NMR (1 H and 31 P) spectroscopic data. Molecular structures of [CpRuCl{η2 -Ph2P{(OC10H6)(μ-CH2)(C10H6O)}PPh2-κP,κP}] (4 ) and [PtCl2{η2 -Ph2P{(OC10H6)(μ-CH2)(C10H6O)}PPh2-κP,κP}] (7 ) are determined by single crystal X-ray studies.
