The Reaction of 3-Methyl-3-butenyl and 3-Methyl-2-butenyl Diphenyl Phosphate with Phenol Derivatives in the Presence of Boron Trifluoride Etherate

Abstract

3-Methyl-3-butenyl diphenyl phosphate reacted with anisol and veratrol in the prgsence of boron triAuoride etfierate- to give p-(3-methyl-2-bgtenyl)gpispl (5), R, =H, (15% yield). and 1, 1-dimethyl-5, 6-dimethoxyindane(6), R=OCHs (18% yield), respectively,
3-Methyl-2-butenyl diphenyl phosphate, prepared by the reaction of 3-methyl-2-buten-1-ol and diphel phenoloridate, reacted with anisol and phenol to give (5), R=-H and p-(3-methyl-2-butenyl)phenol, respectively.
