Title:
PROCESS FOR PRODUCING TRANS-2-BROMOINDAN-1-OL
Document Type and Number:
WIPO Patent Application WO/1996/028406
Kind Code:
A1
Abstract:
An industrial process for producing trans-2-bromoindan-1-ol at a low cost. The trans-2-bromoindan-1-ol of formula (II) can be produced by hydrolyzing 1,2-dibromoindan of general formula (I), (wherein the relative configuration of two bromine atoms at the 1- and 2-positions may be either trans or cis). Alternatively, the compound of the formula (II) can be produced also by brominating indene into 1,2-dibromoindan and hydrolyzing the reaction mixture of the bromination continuously without the isolation of 1,2-dibromoindan. 1,2-Dibromoindan can be produced also by reacting indene with hydrogen bromide in the presence of hydrogen peroxide.
