Reactions of m-chloroperoxybenzoic acid with dimeric cyclopalladated complexes derived from 2-phenyl-2-oxazolines
Cyclopalladated complexes (CPCs) (S,S)-di-mu-Cl(kappa2-C,N)2Pd2 (1a,b) and (S,S)-di-mu-OAc(kappa2-C,N)2Pd2 (7a,b) obtained from (S)-4-t-butyl-(a) and (S)-4-ethyl-2-phenyl-2-oxazoline (b) were reacted with m-chloroperoxybenzoic acid (m-CPBA) at room temperature in methylene chloride, ethyl acetate or acetonitrile followed by workup with lithium chloride. Oxidation products formed in these reactions include dinuclear complexes (S,S)-di-mu-Cl(kappa2-N,O)2Pd2 (2a), (S,S)-di-mu-oxo(kappa2-N,O)2Pd2Cl2 (2b), and (S,S)-di-mu-(m-Cl-C6H4CO2)(kappa2-N,O)2Pd2 (3a,b), mononuclear derivatives (S,S)-bis(kappa2-N,O)Pd (4a,b) and dinuclear monooxidation complexes (S,S)-di-mu-Cl(kappa2-N,O)(kappa2-C,N)Pd2 (5a,b). Each complex was isolated in low yield (6-46 %) with the combined yield of oxidation products reaching up to 64 %. The best selectivity in product distribution was observed for the reactions of mu-OAc-CPCs 7a,b with 2.7 equiv. of m-CPBA in acetonitrile, in which oxygen-insertion adducts 2a and 4b were isolated in 44 and 46 % yields, respectively. The structures of all complexes were supported by spectroscopic methods. An X-ray crystallographic study of compound 4a was performed, confirming its mononuclear structure and revealing an unusual bent geometry.
