Abstract
The organozinc-enamines EtZn[R’N-CH=CH-N(Et)R’] (R =‘Bu (la), ‘pent (2a), ‘Pr (3a)) react with Et,Al via a transmetallation
reaction to the corresponding organoaluminium-enamines Et,Af[R’N-CH=CH-N(Et)R’l (R’ =‘Bu (1~1, ‘pent (2~)) and EtzZn.
Prior to the transmetallation reaction initial 1: 1 zinc-enamine-trialkylaluminium adducts are formed. Compounds lc and tc are
thermally unstable and rearrange via a 1,Zalkyl
