BENZYLDIPHENYLPHOSPHINE Use and Manufacturing

Methods of Manufacturing

General procedure: The selenides of the phosphines 1-8 were prepared by heating (60 C) each phosphine in CDCl3 (0.5 mL) with a three-fold excess of selenium in an NMR tube under nitrogen for 3 hours. Upon cooling to room temperature, the 31P{1H} NMR spectrum of each solution was recorded, and in each case revealed quantitative conversion to the corresponding phosphine selenide. The 31P{1H} NMR chemical shifts and 1JPSe coupling constants of the selenides are provided in Table 1.EXAMPLE 4 Preparation of Benzyldiphenylphosphine from Benzyl Bromide To a solution of 2.7 ml benzyl bromide (20 mmol) in 40 ml DMF, was added 0.436 g NiCl2 (dppe) (0.826 mmol). The reaction mixture was cooled to 5 C. and 3.6 ml ClPPh2 (20 mmol) was added dropwise followed by the portionwise addition of 1.74 g zinc (27 mmol) while the internal temperature was kept at 814 C. The reaction mixture was heated to 83 C. for 45 minutes at which time 81% conversion to the title compound was observed by gas chromatographic analysis.
