Ligand substitution reactions gallium

Kinetic parameters have been obtained for reaction of [Fe(par)2] , par = 4-(2-pyridylazo)resorcinol (37), with cyanide and the mechanism of formation of the product [Fe(CN)3(par)] discussed. A more complicated sequence of steps is involved in the fairly slow displacement of edta from [Fe(edta)]" by hexadentate Schiff base ligands derived from trien and substituted salicaldehydes (38). Kinetic studies were carried out for two such ligands, and it was demonstrated the gallium(III) complexes of such ligands are also fairly inert (cf. Section 8.1). " ... [Pg.182]

The synthesis, structure and bonding of the first aluminium(I) and gallium(I) complexes of phosphine-substituted transition metal centres have been published. These have terminal coordinated Cp E ligands (E = Al, Ga or In). Reaction of [(dcpe)Pt(H)(CH2Bu )] [dcpe = bis(dicyclohexylphosphino)ethane] with Cp E yields the tetrahedrally coordinated complexes [(dcpe)Pt(AlCp )2] (38) and [(dcpe)Pt(GaCp )2]. Quantum chemical calculations suggest rather weak Pt-E bonds for both complexes. [Pg.148]
