Abstract The reaction of racemic N,N-dimethylamino-3-but-l-ene (1) and N,N-dimethylamino-l-cyclohex-2-ene (2) with Li2PdCl4 in 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-dim
摘要外消旋的N,N-二甲基氨基-3-丁-1-烯(1)和N,N-二甲基氨基-1-环己-2-烯(2)与Li2PdCl4在甲醇中于0°C反应生成[Pd( CH2CH(OMe)CH(Me)NMe2)(μ-Cl)] 2(4)和[Pd(CHCH(OMe)CHNMe2(CH2)3)(μ-Cl)] 2(6),分别为单一异构体。另一方面,从(R,R)-α,α-二甲基二苄基烯丙基胺与钯( II)盐。
