Abstract
Novel phosphido cluster complexes of formula (Me(2)M)(4)(mu-(1,2-PR)(2 )C6H4)(2) (M = Al, R = Me (1); M = Ga, R = t-Bu (2)) result when the c helating diphosphine ligand 1,2-bis(alkylphosphino)benzene is mixed wi th trialkylaluminum and -gallium reagents. When the potentially chelat ing ligand 1,2-bis(tert-butylphosphino)ethane is mixed with 2 equiv of AlMe(3) under the same conditions, the secondary phosphine bis-adduct complex Me(3)Al . PH(t-Bu)CH2CH2(t-Bu)HP . AlMe(3) (3) is formed.
