The reaction of bis(trimethylsilyl) telluride with equimolar amounts of pivaloyl chloride affords ButCOTeSiMe3, which exists as a mixture of CO- and CTe-bonded isomers related by a 1,3-silylshiftequilibrium (multinuclear n.m.r. spectroscopic evidence).
双(三甲基甲硅烷基)碲化物与等摩尔量的新戊酰氯反应生成Bu t COTeSiMe 3,它以与C O键和C Te键联的异构体的混合物形式存在,与1,3-甲硅烷基位移平衡相关(多核nmr光谱证据)。
