Novel tridentate phosphines and method of forming aldehyde hydrogenation catalysts

This invention comprises a process for hydrogenation of aldehydes to alcohols using novel homogeneous catalysts. The catalysts are generated in situ under hydrogen and carbon monoxide gases in a suitable solvent, by mixing a rhodium catalyst precursor, such as Rh(CO)2 acetoacetonate and a defined ligand.

CLEAVAGE OF PHOSPHOROUS-CARBON BONDS WITH SODIUM/NAPHTHALENE. FACILE PREPARATION OF UNSYMMETRICAL DIPHOSPHINES

Sodium/naphthalene was found to be a homogeneous, mild and selective reagent for the reductive cleavage of aryl-phosphorous bonds.Such cleavage reactions are very useful in the convenient synthesis of unsymmetrical diphosphines from commercially available and air-stable diphosphines.

Oligophosphine Ligands, I Convenient Syntheses of the Trimethylene-linked Triphosphines RP2 and their Precursors Ph2P(CH2)3P(H)R (R=Ph, Me)

The secondary-tertiary diphosphines Ph2P(CH2)3P(H)Ph (2) and Ph2P(CH2)3P(H)Me (3) have been prepared from Ph2P(CH2)3Cl (1) and NaP(H)Ph or LiP(H)Me, respectively.Metallation of 2 and 3 with n-butyl lithium and further reaction of the lithio-derivatives with one equivalent of 1 yields PhP2 (4) and MeP2 (5).The tritertiary phosphines 4 and 5 have likewise been obtained from RPLi2 (R=Ph, Me) and two equivalents of 1.The synthesis of 4 from PhPCl2 and two equivalents of the Grignard reagent of 1 is also reported.Each of the phosphines 1-5 was characterized by NMR and mass spectroscopy. - Keywords: Secondary-tertiary Diphosphines, Tritertiary Phosphines, Preparation, NMR Spectra, Mass Spectra
