METHOD OF OBTAINING POLYCYCLIC 3-PHENYLPHOSPHOLANE-3-SULPHIDES Russian patent published in 2015 - IPC C07C319/00 C07F9/547 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of obtaining compounds, suitable for the field of the organic synthesis of formulae 1 a-d The method consists in the interaction of skeletal hydrocarbon on a norbornene series of bicycle[2.2.1]heptene-2, or exo-tricyclo[3.2.1.0^2.4]octane-6, or tetracyclo[4.3.0^2.4.0^3.7]nonen-8, or dicyclopentadiene with triethylaluminium at the molar ratio of unsaturated compound: AlEt₃=1:1.05-1.2, in the presence of 1-10 mol% of the catalyst zirconcene dichloride (Cp₂ZrCl₂) in an argon atmosphere at 15-25°C and atmospheric pressure with the following addition of toluene, benzene or hexane and halogenide of trivalent phosphorus RPCl₂ (where R=Ph) in the quantity of 1:1 (mole/mole) relative to triethylaluminium and mixing of the reaction mass in an argon atmosphere at 15-25°C, after which the equimolar to phenyldichlorphosphine quantity of molecular sulphur S₈ is introduced.

EFFECT: effective method of obtaining polycyclic phospholanesulphides is claimed.
