Optimized geometries of all the dimers indicated that while the DTT moieties on two sides of the boron are semiplanar to each other, the mesityl group of boron atom remained vertical with reference to DTT groups.
MeO, |Me.sub.2~N, |Ph.sub.2~P, ferrocenyl, etc.), Y is a conjugated |pi~-linker including aryl, vinyl, or ethynyl groups or combinations thereof, and mes is the mesityl group, 2,4,6-|Me.sub.3~C6|H.sub.2~.
The mesityl group was selected for synthetic convenience rather than for its electronic properties.
The essential oil compositions were evaluated by GC- MS analysis and identified twenty four compounds as 94.37% of the total essential oil, where cyclohepta-1,3,5,-triene (16.07%), 2H-1,4-pyridoxazin-3(4H)-one (12.27%), L-carvenol (8.04%), p- cymene (9.15%), a-terpineol (7.98%), b-sitosterol (6.76%), tyranton (6.42%), mesityl oxide (6.34%), -terpinene (5.42%) and b-linalool (3.74%) were the major constituents.
Twenty four different chemical compounds were identified and quantified from the oil, where cyclohepta-1,3,5,-triene(16.07%),2H-1,4pyridoxazin-3(4H)-one (12.27%), L-carvenol (8.04%), p-cymene (9.15%), a-terpineol (7.98%), b-sitosterol (6.76%), tyranton (6.42%), mesityl oxide (6.34%), -terpinene (5.42%) and b-linalool (3.74%) etc.
This activity of the essential oil could be assigned to the presence of cyclohepta-1,3,5,-triene, 2H-1,4-pyridoxazin-3(4H)- one, L-carvenol, p-cymene, a-terpineol, b-sitosterol, tyranton, mesityl oxide, -terpinene and b-linalool [31, 32].
of acetone to diacetone alcohol with the subsequent dehydration of the diacetone alcohol to yield mesityl oxide over an acidic ion exchange resin catalyst.
The mesityl oxide/water binary is an excellent example as it is a heterogeneous azeotrope.
Other important issues were addressed such as how one deals with a very toxic material such as mesityl oxide.
