Cyclicolefins usually give Heck products having an aryl ring residing at the allylic or homoallylic position. We describe herein a new method that allows arylation at the vinylic position of various cyclicolefins.

The 4-aryl-1-(biarylmethylene)piperidine compounds are piperadine compounds having a biaryl substituent linked to the nitrogen atom of the piperidine ring by a methylene (—CH
2
—) group, and an aryl moiety attached to the 4-position of the piperidine ring. The aryl moiety may be a methoxy quinoline group, a 2-oxo quinoline group, or a 2-oxo, 3,4-dihydroxy quinoline group. The biaryl substituent may be biphenyl, fluorophenyl benzene, 3-phenyl pyridine, 3-(4-fluorophenyl) pyridine, phenyl cyclopentene, or 3-(1-cyclopenten-1-yl) pyridine. The compounds are believed to be suitable for anti-psychotic medication, since they are structurally related to SLV-313, a potential atypical antipsychotic having potent D
