Abstrakt: The reaction of racemic N,N-dimethylamino-3-but-l-ene (1) and N,N-dimethylamino-l-cyclohex-2-ene (2) with Li2PdCl4in methanol at 0°C yielded [Pd(CH2CH (OMe)CH(Me)NMe2)(μ-Cl)]2(4) and [Pd(CHCH(OMe)CHNMe2(CH2)3)(μ-Cl)]2(6), respectively, as single isomers. On the other hand, only the deallylation product trans-PdCl2[NH-(R,R)-(MeCHPh)2]2(8) was isolated from the reaction of (R,R)-α,α-dimethyldibenzylallylamine with palladium(II) salts.
