Ring closure reaction of 4-tert-butyl-4- penten-1-ol with electrophilic reagents

Abstract

101-105The reaction of 4-tert-butyl-4-penten-1-ol <span style="font-size:15.5pt; mso-bidi-font-size:9.5pt">3<span style="font-size:15.5pt;mso-bidi-font-size: 9.5pt"> with some electrophilic reagents (such as mineral acids, mercuric acetate, peracids) has been investigated. It is found that in the acid (H2SO4)catalysed reaction of 3, the products of 1,2- methyl rearrangement are produced. The oxymercuration/demercuration reaction of 3 and its reaction with meta-chloroperbenzoic acid afford in high yields exclusively Markovnikov-type products.   </span
