Synthesis of Anti-Cis-Phosphiranes

A method for the preparation of three-membered phosphoric heterocycles-phosphi-ranes by reaction of dilithium derivatives of tertiary phosphines with tetrachloromethane is described. The reaction is stereoselective and leads to the formation of anti-cis(meso)-2,3-diphenylphosphiranes. Phosphiranes were isolated as individual compounds and their structure was confirmed by 1H, 13C, and 31P NMR spectra, and mass spectra. The present method is simple and can be successfully used for the preparation of some types of phosphiranes that are inaccessible by other methods.

Reactions of elemental phoshorus and phosphine with electrophiles in superbasic systems: XIX. Formation of the C-P bond with participation of elemental phosphorus under microwave assistance

Microwave irradiation facilitates phosphorylation of aryl methyl chlorides and styrene with red phosphorus in the presence of strong bases and increases the yield of the main products, tertiary phosphine oxides. Nauka/Interperiodica 2007.

Reactions of elemental phosphorus and phosphine with electrophiles in superbasic systems: XVI. Phosphorylation of benzyl chloride with elemental phosphorus and phosphine

The major product of the reaction of benzyl chloride with red phosphorus in the system concentrated aqueous KOH-dioxane-phase-transfer catalyst (43-95°C, Ar) is tribenzylphosphine oxide (yield up to 61%). Under similar conditions, phosphorylation of benzy

The reaction of N-dichlorophosphoryl-P-trichlorophosphazene with alkyl grignard reagents

The reactions of N-dichlorophosphoryl-P-trichlorophosphazene Cl3P=N-P(O)Cl2 (1) with benzylmagnesium bromide, 2-phenylethylmagnesium bromide, trimethylsilylmethylmagnesium chloride, n-butylmagnesium bromide, cyclohexylmagnesium bromide, cyclopentylmagnesium bromide, tert-butylmagnesium bromide, iso-propylmagnesium bromide, and ethylmagnesium bromide were studied. Tri- and pentaalkyl phosphazenes were obtained in very poor yield from trimethylsilylmethylmagnesium chloride and cyclohexylmagnesium bromide, respectively. Trialkylphosphoryl compounds formed from benzyl-, 2-phenylethyl-, and n-butylmagnesium bromide. No phosphorus compound could be isolated from the reaction of 1 with t-butyl-, cyclopentyl-, iso-propyl-, and ethylmagnesium bromide.

Reactions of elemental phosphorus and phosphines with electrophiles in superbasic systems: XII. Synthesis of unsymmetrical tertiary phosphine oxides from red phosphorus and organyl halides

Alkyldibenzyl- and benzyldialkylphosphine oxides were prepared in one stage by direct phosphorylation of a mixture of alkyl bromides and benzyl chloride with red phosphorus under the conditions of phase-transfer catalysis (concentrated aqueous KOH solution-dioxane-benzyltriethylammonium chloride).

Generation of phosphide anions from phosphorus red and phosphine in strongly basic systems to form organylphosphines and -oxides

Generation of phosphide anions from phosphorus red or phosphine under the action of strong bases followed by their reactions with organyl halides, electrophilic alkenes and alkynes proves to be the most straightforward and well-controlled route to mono-, di-or triorganylphosphines or phosphine oxides of diverse structure.
