METHOD OF PRODUCING 3-ALKYL-3-METHYL-1-PHENYL-3-OLS Russian patent published in 2016 - IPC C07C29/40 C07C33/20

Abstract RU 2596878 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing 3-alkyl-3-methyl-1-phenyl-3-ols of formula (1), where R=CH₃, C₂H₅, C₄H₉, C₆H₁₃, which are used as precursors in synthesis of natural compounds, having various biological activity, which can be used in pharmaceutical industry for synthesis of medicinal preparations, as well as forming light-fast coatings.

EFFECT: method comprises reacting styrene with ethylaluminium dichloride (EtAlCl₂) and ketone of general formula MeCOR, where R=CH₃, C₂H₅, C₄H₉, C₆H₁₃, in presence of magnesium (Mg, powder) and a Cp₂ZrCl₂ catalyst in molar ratio styrene:MeCOR:[Al]:Mg:[Zr] = 10:10:(20-30):(10-14):(0 8/10-1 2/10) in tetrahydrofuran in an argon atmosphere at 20-22 °C and atmospheric pressure for 8 hours.
