Effects of Structure on the Free Radical Reactions of Hydridophosphoranes with Dimethyl Sulfide

“…Hydridophosphorane 2 was prepared by the method of Wolf et al Hydridophosphoranes 1 8 and 3 8 were obtained from Professor J. C. Martin. Preparations of 4 , 5 , 6 , 7 , 8 , and 9 were previously reported. Benzene was distilled over calcium hydride and stored over 4 Å molecular sieves.…”

The Atherton-Todd reaction of hydridophosphoranes

“…To a stirred solution of hydridophosphorane 1 [9] (20 mmol) in 10 mL acetonitrile or dichloromethane were added tetrachloromethane (40 mmol), triethylamine (60 mmol), and the selected nucleophilic reagent (40 mmol) (dimethylamine was passed in as a gas) at room temperature. The reaction mixture was stirred at ambient temperature for several hours until the 3'P NMR signal of hydridophosphorane 1 disappeared; then the mixture was filtered, and the filter cake was washed with ethyl ether.…”

Computer Design of Synthesis in Phosphorus Chemistry: Automatic Treatment of Stereochemistry

“…, let us replace Sinc;• by Sine,• U Sident,•. Thus, in Figure 10, for Sinc2 = (6,18), and Sident6 = (6,8), Sr = (6), and we replace Sinc2 by (6,8,18). If Sr is empty, then Sic,• is kept unchanged.…”
