烷基氢化物InIr(R)(H)[Ln={MesHSi(CH2)2PPh2}(PMe3)2，R=Me，Et]的热分解导致烷烃的还原消除生成16e Ir(I)物种InIr(A)。中间体A经历了分子内C-H键的活化。A与甲醇的反应表明，A发生了[1，2]H从硅原子到Ir中心的移动，可逆地得到了氢化物Ir(H){η2-Messi(CH2)2PPh2}(PMe3)2(B)。
Thermolysis of alkyl-hydrido complexes, LnIr(R)(H) [Ln = {MesHSi(CH2)2PPh2}(PMe3)2, R = Me, Et], caused the reductive elimination of alkane to generate a 16e iridium(I) species LnIr (A). Intermediate A underwent the intramolecular C–H bond activation. Reactivity of A with MeOH revealed that A underwent a [1,2] H shift from the silicon atom to the iridium center to give hydrido(silylene) complex Ir(H){η2-MesSi(CH2)2PPh2}(PMe3)2 (B) reversibly.
