Synthesis and characterization of dialkylaluminum, -gallium or -indium[2-(2-pyridyl)]ethoxides

Controlling the stereoselectivity of rac-LA polymerization by chiral recognition induced the formation of homochiral dimeric metal alkoxides

Chiral recognition of monomeric Me₂MOR units resulting in the formation of homochiral dimeric species [Me₂M(μ-OR)]₂(M = Ga, In), leads to heteroselective catalysts for the ring opening polymerization ofrac-lactide (rac-LA).

Diorganogallium Complexes Containing Tripodal Schiff Bases: Synthesis and Structure of [N{Me2GaO(C6H4)CH=N–CH2–CH2-}3]

Treatment of triorganogallium etherates with tripodal Schiff bases in benzene gave complexes of composition [N{R2GaO(C6H3X)CH=N–CH2–CH2–}3] (R = Me, Et; X = H, OMe) in nearly quantitative yield. The molecular structure of [N{Me2GaO(C6H4)CH=N–CH2–CH2–}3] revealed that there are two different types of molecules in the crystal lattice each containing three distorted tetrahedral gallium atoms.
