FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing 2,3-dialkyl-1-phenyl(alkyl)phosphol-2-ene-1-sulphides, which can be used in organometallic chemistry and catalysis as effective intermediates and ligands, and as precursors in production of LEDs and phosphosugar derivatives. The method includes reacting disubstituted acetylenes with triethylaluminium in the presence of a zirconocene dichloride catalyst (Cp2ZrCl2) in toluene in an argon atmosphere at 20-40°C and atmospheric pressure for 4-12 hours, followed by addition at (-5) to (-10)°C of phenyl- or alkyl dichlorophosphine, taken in equimolar ratio to Et3Al, and mixing at room temperature for 10-30 minutes. Subsequent reaction of the obtained phospholenes with S8 in chloroform for 4-6 hours produces the corresponding phospholene-1-sulphides with output of 32-90%.
EFFECT: improved method.
