together with the derivatives 1T2 and 4T2 published previously. The piperidine ring adopts a chair conformation. In all structures, the aryl group is in the axial position, with the plane through the aryl C-atoms nearly perpendicular to the mirror plane of the piperidine ring. The through-bond interaction between the piperidine ring N-atom (one-electron donor) and the substituted exocyclic CC bond (acceptor)
