Interconversion of stereoisomeric cycloorganosiloxanes |
| abstract |
Stereoisomers of cycloorganosiloxanes are interconverted without siloxane bond redistribution by reacting the cyclic siloxane with anhydrous zinc chloride, zinc bromide, ferric chloride, aluminum chloride or aryl phosphonium chlorides in the presence of nitro compounds or aryl phosphate esters as solvents. A typical example is the conversion of 2,6-trans-diphenylhexamethylcyclotetrasiloxane to the 2,6-cis-isomer by heating in 2-nitropropane solvent in the presence of anhydrous zinc chloride. |
