Porphyrin–carborane organometallic assemblies based on 1, 2-dicarba-closo-dodecaborane (12) ligands

The assembly of soluble, air-stable, supramolecular structures {(Zn-TPyP)[Cp*Ir{S2C2(B10H10)}]4(THF)2}(2), {(Cu-TPyP)[Cp*Ir{S2C2(B10H10)}]4(THF)2}(3) and {(Zn-TPyP)[Cp*Ir{S2C2(B10H10)}]2.6(CHCl3)}n (4), based on metal-containing moieties [Cp*Ir{S2C2(B10H10)}] (1) bridged by nitrogen-based organic spacers, are described.

Tetrametallic clusters (Ir2Rh2) through an ancillary ortho-carborane-1,2-dichalcogenolato ligands

The tetrametallic cluster complexes {Cp*Ir[E(2)C(2)(B(10)H(9))]}Rh(2)(cod){Cp*Ir[E(2)C(2) (B(10)H(10))]} (E = S; Se) have been synthesized by reactions of the 16-electron half-sandwich iridium complexes [Cp*Ir{E(2)C(2)(B(10)H(10))}] [Cp* = eta(5)-C(5)Me(5), E = S, Se] with [Rh(cod)(micro-OEt)(2)] at room temperature in toluene solution. In the solid state, this tetrametallic cluster exhibits an irregular nearly planar metal skeleton with the two carborane dichalcogenolato ligands bridging the four metal centers from both sides of the tetrametallic plane. Even though all metal atoms coordinate bridging chalcogen atoms, they show different electronic and coordination environments. The molecular structures of and have been determined by X-ray crystallography.

A non-noble amorphous Co–Fe–B catalyst highly selective in liquid phase hydrogenation of crotonaldehyde to crotyl alcohol

A nanosized amorphous Co–Fe–B catalyst exhibited higher selectivity and yield to crotyl alcohol than noble Pt-based catalysts in the hydrogenation of crotonaldehyde and could be prepared by a facile chemical reduction method.

Highly selective amorphous Ni–Cr–B catalyst in 2-ethylanthraquinone hydrogenation to 2-ethylanthrahydroquinone

A nanosized amorphous Ni-Cr-B catalyst prepared by the chemical reduction method exhibited superior thermal stability and selectivity in hydrogen peroxide synthesis via the anthraquinone route.
