Synthesis and isomerization of 1,2-bis (indenyl) ethanes

摘要

A solution of an alkali metal alkoxide having the formula MOR, wherein M is an alkali metal and R is a hydrocarbyl group having one to ten carbon atoms in a non-interfering ether solvent and wherein the solution contains from about 10 mol percent to about 20 mol percent of the alkali metal alkoxide. A method doe isomerisation of a compound of Formula I, wherein the Formula I compound is unsubstituted or substituted with the same substituents at one or more of the available ring positions 2 to 7 and 2' to 7', which comprises treating said Formula I compound with a solution of claim 1.
