- TRIVINYLCYCLOHEXANE STEREOISOMERIC COMPOSITIONS AND METHODS FOR PREPARING SAME
-
Disclosed herein is a process for making 1,2,4-trivinylcyclohexane that is enriched in a particular geometric isomer. The process involves the thermal isomerization of 1,5,9- cyclododecatriene at temperature between 400°C and 600°C followed by an equilibration of the resultant intermediate in either the gas phase or liquid phase at temperature between 180°C and 375°C and at pressures ranging from 0.101 kPa to 1,013 kPa. Also disclosed are 1,2,4-trivinylcyclohexane compositions that are enriched in a particular geometric isomer.

- CIS-TRIS--?-HOMOBENZENE - SYNTHESIS AND THERMOLYSIS
-
The cis-tris--?-homobenzene 7 has been synthesised.From vapour phase thermolyses (400-500 deg C) it is concluded, that the ?2s+?2s+?2s>-cycloreversion reaction is - at most - only a minor pathway in the thermal stabilisation of 7.
