At 110 °C α-substituted [Fe2(CO)6(µ-PhCCH2)(µ-PPh2)] 1 is cleanly converted into the β-isomer [Fe2(CO)6(µ-HCCHPh)(µ-PPh2)] 2, a process which is accelerated in the presence of arylphosphines; with P(OMe)3 mono- and di-substituted adducts of 1 are isolated at 70 °C, which cleanly isomerise at higher temperatures.
在110°C下,α-取代的[Fe2(CO)6(µ-PhCCH2)(µ-PPh2)] 1可完全转化为β-异构体[Fe2(CO)6(µ-HCCHPh)(µ-PPh2)] 2,在芳基膦存在下,这一过程会加速;在70°C下,可分离出1的单取代和二取代加合物P(OMe)3,在更高的温度下,它们可完全异构化。
