- Single-stage synthesis of alkyl-H-phosphinic acids from elemental phosphorus and alkyl bromides
-
Elemental phosphorus (red or white) reacts with alkyl bromides at 60–62 °C in the phase-transfer catalytic system KOH/H2O/PhMe/Et3BnNCl to afford alkyl-H-phosphinic acids in up to 47% yield.

- SUPERBASE-INDUCED GENERATION OF PHOSPHIDE AND PHOSPHINITE IONS AS APPLIED IN ORGANIC SYNTHESIS
-
A series of new direct reactions of red phosphorus (or white) with organyl halides, alkenes and acetylenes have been developed.Reactions occur in superbasic systems, such as alkali metal hydroxide-dipolar aprotic complexing solvent (DMSO, HMPA) or under phase-transfer conditions to afford earlier inaccessible triorganylphosphines and -phosphine oxides including unsaturated ones in good yield.
