Cationic ethylzinc compound: a benzene complex with catalytic activity in hydroamination and hydrosilylation reactions.
The tight ion pair [EtZn(η(3)-C(6)H(6))][CHB(11)Cl(11)]·C(6)H(6) (1·C(6)H(6)) was obtained through β-hydrogen abstraction and concomitant ethene elimination from Et(2)Zn with the trityl salt [Ph(3)C][CHB(11)Cl(11)]. This ionlike species shows catalytic activity in hydrosilylation and intramolecular hydroamination reactions. The amine adduct {CH(2)CHCH(2)C(Ph(2))CH(2)NH(2)}(3)ZnCB(11)Cl(11) (3), which features a rare transition metal-carborane σ bond, was isolated from a hydroamination experiment.
