Abstract
Treatment of ( η 5-C 5Me 5)Ru( η 3-C 3H 5)Cl 2 in CH 2Cl 2 with ethereal diazomethane in the presence of copper powder produces ( η 5-C 5Me 5)Ru( η 3-C 3 H 5)(CH 2Cl)Cl in moderate yield with no detectable formation of the bis(chloromethyl) derivative. Deuterium labeling with CD 2N 2 shows no methylene scrambling into the allyl ligand. Evidence from NMR spectroscopy supports an endo allyl conformation in the chloromethyl complex. Mass spectroscopy experiments indicate that the d 4 (Ru IV) metal center is relatively ineffective in stabilizing the ( η 5-C 5Me 5)Ru( η 3-C 3H 5) ( = CH 2)Cl] + fragment. The new chloromethyl complex reacts under photochemical conditions to give polymethylene with the regeneration of the starting dichloride. No intramolecular transfer of methylene to the allyl or ( η 5-C Me 5) ligands is observed.
