Abstract
Abstract The preparation of a series of complexes, II–XIII, containing the 1-formylpropylpalladium(II) moiety from di-μ-chlorobis[3-(dimethylamino)-1-formyl-2,2-dimethyl- C,N ]dipalladium(II) (I) is described, and the structures of these complexes are discussed in terms of their 1 H NMR and IR spectra. The relatively low values for ν(C O) are consistent with the presence of a metal-carbonyl group interaction and the influence of changes in the coordination sphere on this interaction is discussed. Reaction of I with allyl bromide or benzyl chloride gave the η 2 -vinyl ether complexes (XV and XVI) while methyl iodide and n-butyl chloride failed to react. I resisted insertions into the Pd C bond when treated with methyl acrylate, diphenylacetylene, or phenylacetylene. In the last of these, consumption of both acetylene and I was observed, the former by self-condensation and the latter with release of the hydrochloride of 3,3-dimethyl-4-dimethylaminobutanal which exists in the cyclic form XVIII.
