Article abstract of DOI:10.1016/0022-328X(84)80664-6

A new, improved method is described for the preparation of cyclopalladated benzalimines; it consists of reacting the ortho-bromobenzalimine with bis(dibenzylideneacetone)palladium(0).A number of substituted o-bromobenzalimines has been studied; the bridged bromide dimers and the corresponding bromo(N-substituted benzalimine-6,C,N)triphenylphosphinepalladium(II) complexes have been fully characterised and 1H and 13C NMR spectral data recorded.In the cases of the N-phenylbenzalimines studied, bis(triphenylphosphine) complexes were also isolated and characterised.
