Abstract
The new imine ligand (E)-2,4,6-Me3C6H2CH2N:CHtBu (1) has been prepd. from 2,4,6-trimethylbenzylamine and trimethylacetaldehyde. In this imine, the ortho-positions of the benzyl group are blocked by Me groups, and there are no ?-hydrogen atoms susceptible for imine-enamine rearrangement. Thus, reaction with [PdCl2(C6H5CN)2] leads to the complex trans-[PdCl2(2,4,6-Me3C6H2CH2N:CHtBu)2] (2) that cannot undergo cyclopalladation. The single-crystal x-ray structure anal. of trans-[PdCl2(2,4,6-Me3C6H2CH2N:CHtBu)2] (2) confirms the trans-coordination of the imine ligands in this square-planar complex. [on SciFinder(R)]
