Charge-compensated Zn metallocenes with σ-/π-chelating carboranyl ligands for the formation of constrained geometry Ru(II) and Ni(II) complexes.
Charge-compensated zinc metallocenes of types [(η(3)-C(2)B(9)H(10))(2)Zn][(η(1)-NMe(2))ZnEt](2) (5) and [{η(3)-(Me)C(2)B(9)H(9)}(2)Zn][(η(1)-NMe(2))ZnEt](2) (6) were produced by reacting σ-/π-chelating aminoalkyl dicarbollides, 7-Me(2)N(H)CH(2)-7,8-C(2)B(9)H(11) (1) and 7-Me(2)N(H)CH(2)-8-Me-7,8-C(2)B(9)H(10) (2), with diethylzinc. Zincocene 5 proved to be an excellent synthon for the formation of dicarbollide-based σ-/π-type constrained Ru and Ni complexes.
