Synthesis and structure of aluminium amine-phenolate complexes
Reaction of Al(OiPr)3 with the tris-phenol amine ligand L1H3 in toluene at ambient temperature results in the formation of the iso-propanol adduct [HOiPr·Al(L 1)]. Single crystal X-ray diff

Diverse Molecular Architectures of Si and Sn [4.4.3.01,6]Tridecane Cages Derived from a Mannich Base Possessing Semi-Rigid Unsymmetrical Podands
Three novel atrane-like pentacoordinate silicon and hexa- and mixed penta- and hexacoordinate tin compounds containing [4.4.3.0]tridecane cages have been synthesized. In the present work, the bis-phenol amine tetradentate ligand, N,N-bis(2-hydroxy-3,5-dim
Dinuclear Aluminum Poly(phenolate) Complexes as Efficient Catalysts for Cyclic Carbonate Synthesis
A series of dinuclear aluminum complexes 1-4 stabilized by amine-bridged poly(phenolato) ligands have been synthesized, which are highly active in catalyzing the cycloaddition of epoxides and CO2. In the presence of 0.3 mol % complex 3 and 0.9 mol % NBu4Br at 1 bar CO2 pressure, terminal epoxides bearing different functional groups were converted to cyclic carbonates in 60-97% yields. Complex 3 is one of the rare examples of Al-based catalysts capable of promoting the cycloaddition at 1 bar pressure of CO2. Moreover, reactions of more challenging disubstituted epoxides also proceeded at an elevated pressure of 10 bar and afforded cyclic carbonates in 52-90% yields.
An unsupported metal hydroxide for the design of molecular μ-oxo bridged heterobimetallic complexes
A terminal and unsupported chromium(iii) hydroxide is reported. The terminal hydroxide is used to synthesize the first example of a heterobimetallic Ti-O-Cr compound containing an unsupported μ-oxo bridge. The heterobimetallic complex exhibits a new absor
