The reaction of [RhCl(COD)]2 (COD = 1,5-cyclooctadiene) with racemic PPh2(CH(Ph)CH2CHO) and pyridine (py) led to the oxidative addition of the aldehyde, and a single geometric isomer of [RhHCl(PPh2(CH(Ph)CH2CO))(py)2] (1), with hydride trans to chloride, was obtained as a mixture of two diastereomers in a 95 : 5 ratio; this was in agreement with density functional theory (DFT) calculations. In a chloroform
[RhCl(COD)] 2(COD =
1,5-环辛二烯)与外消旋PPh 2(CH(Ph)CH 2 CHO)和
吡啶(py)的反应导致醛的氧化加成,并且一个单一的几何构型得到[RhHCl(PPh 2(CH(Ph)CH 2 CO))(py)2 ](1)的异构体,
氢化物以反式转化为
氯化物,为两种非对映体的比例为95:5的混合物;这与密度泛函理论(DFT)的计算是一致的。在
氯仿溶液中,
氯化物与
氢化物交换产生[RhCl 2(PPh 2(CH(Ph)CH 2 CO))(py)2 ](2),因为动力学优选的物质的混合物,反式-py-2A两种非对映,和,顺-Cl-2B'和CIS -Cl-2B,与顺式的
吡啶和
氯化反式到酰基; 根据DFT计算所预测,后者是主要物种。复杂1反应带外消旋PPH 2(CH(PH)CH 2 CHO)或PPH 2(ø -C 6 ħ 4 CHO),得到[RhHCl(PPH 2(CH(PH)CH
