FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing tricyclohexylphosphine, used in synthesis of metal complex catalysts for the following reactions: metathesis, carbonylation, cross linking, polymerisation etc. The proposed method involves reacting red phosphorus with cyclohexyliodide and iodine, taken in molar ratio of 1:3:0.1 at temperature from 215 to 220°C in an inert atmosphere. The formed dimeric iodine complex of tricyclohexylphosphine is treated with pyridine or toluene with addition of 2 equivalents of pyridine in terms of red phosphorus and zinc powder.
EFFECT: design of a novel efficient and safe method of producing tricyclohexylphosphine.
