Cationic Ethylzinc Compound: A Benzene Complex with Catalytic Activity in Hydroamination and Hydrosilylation Reactions
The tight ion pair [EtZn(eta(3)-C6H6)]-[CHB11Cl11]center dot C6H6. (1 center dot C6H6) was obtained through beta-hydrogen abstraction and concomitant ethene elimination from Et2Zn with the trityl salt [Ph3C][CHB11Cl11]. This ionlike species shows catalytic activity in hydrosilylation and intramolecular hydroamination reactions. The amine adduct {CH2CHCH2C(Ph-2)CH2NH2}(3)ZnCB11Cl11, (3), which features a rare transition metal-carborane a bond, was isolated from a hydroamination experiment.
