Abstract

Abstract The acid-catalysed rearrangement of the cyclohex-2-en-1-ols 15, d 3-15, 16, 17 and 19, the cyclohexa-2, 5-dien-1-ols 20 and 21, and also the allyl alcohols 22 and 23 (Scheme 3), using 98-percent sulfuric acid/acetic anhydride 1: 99 at room temperature, was investigated. From the rearrangement of 4-allyl-4-phenyl-cyclohex-2-en-1-ol (15), with reaction times greater than 2 hours a single product is obtained, 4-allyl-biphenyl (50) in 33 ...
