Abstract Polyisocyanides with the groups -CH2N ≡ C and -C(O)O(CH2)2N≡C attached to polystyrene have been prepared and reacted with various metal carbonyl compounds resulting in the fixation on the polymeric supports of-M(CO)5, -M(CO)4 (M = Cr, Mo, W), -MO(Cl)(η-C5H5)(CO)2, -Mn2(CO)η -Mn(CO)ηX (N = 3, 4; X = Cl, Br), -Fe(CO)4, -Fe3(CO)11, -FeI2(CO)2, -FeX(η-C5H5)(CO) (X = Cl, Br, I), -Ru(CO)4, -Ru3(CO)9, ,,-Os3H2(CO)10", and -RhCl(CO)2. The cyano complexes [Fe(CN)2(η-C5H5)CO]- and [Mo(CN)2(η-C5H5)(CO)2]- have been immobilized by alkylation with chloromethylated polystyrene

Pentamethylendiazirine (N͡=N) has been found in metal carbonyl compounds as a monodentate two electron ligand (π-CH3C5Η4Mn(CO)2 N͡=N, (OC)5W N͡=N) or as a bidentate four electron ligand ((OC4M (N͡=N)2M(CO)4 (M = Mo, W), (OC)4Fe N͡=N Fe(CO)4). The reaction of Fe2(CO9 with diazirine affords the isocyanate and/or methylenamino-bridged complexes (OC)3Fe(NCO) (N=C< )Fe(CO)3 and (OC)3Fe (N=C< )2Fe(CO)3.


In this paper, we survey the synthesis, structure and bonding of a series of cluster carbonyl compounds of ruthenium and osmium containing from three to ten metal atoms. Members of this series include neutral, anionic hydrido and carbido clusters, all of which are derived from their [M 3 (CO) 12 ] parent. In general, the synthesis of these compounds involves the pyrolysis of either [M 3 (CO) 12 ] or, with osmium, some higher nuclearity cluster. The mechanism by which these reactions occur is believed to involve the form ation of highly unstable, unsaturated derivatives. Many of these clusters contain frameworks of metal atoms that may be regarded as fragments of close-packed metallic arrangements; others may be regarded as examples of tetrahedral growth patterns. They exhibit a new and diverse chemistry, much of which may now be understood in terms of simple bonding arguments.
