Hydrogenation and isomerization of allylbenzene in the presence of the (Cp2TiCl)2-LiAlH4 catalytic system
1989
1.
The (Cp2TiCl)2-LiAlH4 system with Al/Ti from 0.25 to 1.5 catalyzes both the homogeneous hydrogenation and isomerization of allylbenzene.
2.
In an argon atmosphere, allylbenzene is isomerized to trans-propenylbenzene with 90–92% selectivity when Al/Ti=1–1.5.
3.
The possibility was demonstrated for reactivation of this catalytic system by its retreatment with LiAlH4.
