HMePhSiSiMe 3在催化量的Ir{η2-Me 2Si（CH 2）2 PPh 2}（PMe 3）3存在下的热分解导致取代基的重新分布，生成其异构体HMe 2SiSiMe 2 Ph。我们提出的机制涉及的甲硅烷基（亚甲硅烷基）的配合物，这是作为一个供体稳定的甲硅烷基（亚甲硅烷基）铱（III）配合物被捕获的1，3-Me-移位。
Thermolysis of HMePhSiSiMe3 in the presence of a catalytic amount of Ir{η2-Me2Si(CH2)2PPh2} (PMe3)3 resulted in the redistribution of substituents to give its isomer HMe2SiSiMe2Ph. We propose the mechanism involving the 1,3-Me-shift on a silyl(silylene) complex, which was trapped as a donor-stabilized silyl(silylene)iridium(III) complex.
