SINGLE-REACTOR METHOD OF PRODUCING DIASTEREOMERICALLY PURE FUNCTIONALLY SUBSTITUTED OLIGOMERS OF PROPENE Russian patent published in 2019 - IPC C07C31/04 C07C31/08 C07C41/30 C07C29/14 

FIELD: chemistry.

SUBSTANCE: disclosed is a method of producing diastereomerically pure functionally substituted oligomers of propene of general formula (1, 2):

n=3-1, X=AlEt₂ (1), X=OH (2) by reacting propene with an alkylating agent in the presence of a catalyst and methylalumoxane followed by oxidation and hydrolysis, characterized in that the alkylating agent used is AlEt₃, as catalyst – rac-[Me₂Si(η⁵-C₉H₁₀)₂]ZrCl₂, reaction is carried out in molar ratio [Zr]:[AlEt₃]:[Al_MAO]=1:200:(40–50), temperature 20 °C and propene pressure of 1 atm for 24 hours in dichloromethane, formed product 1 by subsequent oxidation with dry O₂ for 2 hours and hydrolysis with 10 % HCl solution is converted into product 2.

EFFECT: design of a single-reactor method of producing diastereomerically pure functionally substituted oligomers of propene of general formula (1, 2).
