The novel electrophilic organo-tantalum catalyst AlS/TaNp () (Np = neopentyl) is prepared by chemisorption of the alkylidene Ta(CHtBu)Np onto highly Brønsted acidic sulfated alumina (AlS). The proposed catalyst structure is supported by EXAFS, XANES

Several ammonium carborane salts ([HNR3][HCB11X11], X = H, Me, Cl) were prepared and evaluated as activators with bis-metallocene and constrained geometry precatalysts at 140 and 190 °C. Activators...

We report the synthesis of PAlP and PBP pincer complexes of Rh with a central bis(N-pyrrolyl)aluminyl or -boryl unit. Complex (PAlpyP)Rh(CO)2 possesses an aluminyl site stabilized by coordination of pyridine, resulting in a four-coordinate Al. Attemp

A series of binuclear homo- and heterobimetallic complexes of the general type (PNP)M-[linker]-M(PNP) have been prepared (M = Ni, Pd, Pt; PNP = a diarylamido/bis(phosphine) pincer ligand; -[linker]- = -C≡C-, -C≡CC≡C-, -C≡CC

Syntheses of a new tripodal alane/tris(phosphine) ligand (AlP3) based on 2-(diisopropylphosphino)pyrrole, and AlP3-supported Ni complexes are reported. The central tris(pyrrolyl)aluminum moiety acts as a stronger Lewis acid towards Ni than other rela

An alane/tris(phospine) ligand reacts with AgOTf by coordination of three phosphines to the Ag center and transfer of triflate to the tris(pyrrolyl) Al site. Reaction with Ag[HCB11Cl11] results in the coordination of two phosphines to Ag and one to A

Catalytic dehydrogenative diboration (DHDB) of alkyne with HBpin was achieved using [Ir(COD)Cl]2 and other related Ir precursors under CO atmosphere. The selectivity for DHDB over hydroboration was higher in less polar solvents and under higher CO pr
