Patent number: 7608713Abstract: Tertiary phosphines are prepared by reacting a phosphine (PH3 or a primary or secondary phosphine) with a cyclic alpha,beta-unsaturated carbonyl compound having no more than one C?C double bond conjugated with a carbonyl group. The inventive tertiary phosphines can have R groups that are the same or different. The inventive tertiary phosphines may be used as ligands for metal catalysts or as starting materials for preparing phosphonium salts or ylids.Type: GrantFiled: March 8, 2004Date of Patent: October 27, 2009Assignee: Cytec Canada Inc.Inventors: Christine J. Bradaric-Baus, Yuehui Zhou

Publication number: 20090247790Abstract: The present invention relates to a process for preparation of a phosphoromonochloridite in high yield by contacting phosphorus trichloride (PCl3) with an aromatic diol in a solution of one or more organic solvents under reaction conditions sufficient to produce the phosphoromonochloridite. The reaction is carried out by adding a feed solution containing the aromatic diol dissolved in a first organic solvent into a reaction zone containing PCl3, and optionally one or more second organic solvents, the addition being conducted so as to maintain substantially isothermal process conditions. The reaction solution comprises greater than 0.01 to less than 5 mole percent of a nitrogen base.Type: ApplicationFiled: March 17, 2009Publication date: October 1, 2009Inventor: Glenn A. Miller

Publication number: 20090171122Abstract: Novel trivalent organophosphonite ligands having the structure of general formula (I): wherein R is an alkyl or aryl group containing 1 to 30 carbon atoms; Ar1 and Ar2 are aryl groups containing 4 to 30 carbon atoms; R1 to R6 are H or alkyl or aryl hydrocarbon radicals containing 1 to 40 carbon atoms; and X is a connecting group or a simple chemical bond, were developed and found to be very active for hydroformylation processes for ethylenically unsaturated substrates. Catalyst solutions prepared from these ligands with a Rh metal show an unusual “ligand acceleration effect” for simple alkenes, i.e., the hydroformylation activity increases as the concentration of ligand increases, and are capable of producing linear or branched aldehydes under typical hydroformylation conditions.Type: ApplicationFiled: December 8, 2008Publication date: July 2, 2009Applicant: EASTMAN CHEMICAL COMPANYInventors: Yun-Shan Liu, Jody Lee Rodgers
