Thermal reaction of ethyl(hydrido){(2-phosphinoethyl)silyl}iridium(III) complex - Formation of a {(2-phosphinoethyl)silyl}(ethene)iridium complex

摘要

Thermolysis of LnIr(C2H5)(H) [L-n = {eta(2)-Me2Si(CH2)(2)PPh2}(PMe3)(2)] led to the clean formation of a 1 : 1 mixture of ethene complex LnIr(C2H4) and dihydrido complex LnIr(H)(2). The former product is proved to be an efficient precursor of an unsaturated silyliridium(I) species through dissociation of ethene. [References: 15]
