Process for making 11-piperazino-diazepines, oxazepines, thiazepines and azepines

This invention concerns a novel process for the preparation of 6-piperazinyl derivatives of morphantridine and corresponding ring-substituted and hereto analogues thereof, comprising reacting a compound of the formula: SPC1 Wherein A is benzene or thiophene, and X is --CH2 -- or a hetero atom or group, with a complex comprising titanium, zirconium, hafnium or vanadium and a corresponding piperazinyl derivative. The end products are in general known and useful as neuroleptics.
