    铑二膦催化加氢甲酰化的咬角效应的由来
    摘要:
    详细研究了咬合角对铑二膦催化的羰基化反应的影响。合成了一系列自然咬合角在102°至121°之间的黄嘌呤类配体,研究了自然咬合角对配位化学和催化性能的影响。X射线晶体结构测定了配合物(尼克硫磷)Rh(CO)H(PPh 3)和(苯并蒽磷)Rh(CO)H(PPh 3)。与自然咬合角计算相反,在两个晶体结构中均观察到大致相同的二膦咬合角。(二膦)Rh(CO)H(PPh 3)和(二膦)Rh(CO)2的溶液结构通过IR和NMR光谱研究了H配合物。光谱学研究表明,所有(二膦)Rh(CO)2 H配合物在二硬脂酸(ee)异构体与赤道根尖(ea)异构体之间表现出动态平衡。平衡组成不能与计算出的自然咬合角相关联。在1-辛烯的加氢甲酰化中,随着自然咬合角的增加,观察到线性醛形成和活性的选择性增加。对于苯乙烯,发现对线性醛的选择性趋势相同。首次使用(13)确定(二膦)Rh(CO)2 H配合物的CO解离速率快速扫描高
