Abstract The reactions of [CpRu(CO) 2 ] 2 with CX 4 (X = Cl, Br) were found to take place under indoor light conditions as well as in the dark to afford CpRu(CO) 2 X (X = Cl, Br) in excellent yields. Another convenient synthetic route to such ruthenium halide complexes involves the reaction of CpRu(CO) 2 H, prepared “in situ” from Ru 3 (CO) 12 and cyclopentadiene, with CX 4 (X = Cl, Br).

Abstract The tetragonal coordination polymer [Rh(diisocyanobiphenyl) 2 + Cl − ] n was studied as a heterogeneous catalyst in a model reaction involving the hydrogenation and isomerization of 1-hexene under mild conditions. The influence of prehydrogenation and premixing of catalyst and 1-hexene on the hydrogenation rates was investigated. The relatively slow rates of hydrogenation and isomerization appear to be consistent with the presence of a large matrix having a relatively small percentage of active sites.

Abstract The ruthenium(II) complexes (η-R 5 C 5 )Ru(CO) 2 X with R = H, CH 3 and X = Cl, Br, I undergo a facile reaction with nitric oxide under UV irradiation to afford ruthenium(IV) nitrosyl derivatives of the general type (η-R 5 C 5 )Ru(NO)X 2 .

The reactions of BrMn(CO)5 with the non-chelating stereochemically rigid bidentate ligands (L-L) 1,3-, and 1,4-diisocyanobenzene, 4,4′-diisocyanobiphenyl, and 4,4′-diisocyanodiphenylmethane afford well characterized complexes of the types BrMn(CO)4(L-L), BrMn(CO)3(L-L)2, and [BrMn(CO)4]2(L-L). Similar reactions with [RC5H4Mn(CO)2NO]+PF6− gave mixtures of oligomers of the type [(RC5H4MnNO)n(L-L)n+1]n+[PF6−]n.
