Trialkyl(aryl)silanes and -germanes effectively react with metal (Al, Ti) tert-butylate-tert-butyl-hydroperoxide under mild conditions (room temperature, benzene or tetrachloromethane) mainly by the element-hydrogen bond. The character of the products depends on the nature of the element, the structure of the radical bound to it, and the solvent. The process is radical in nature. It includes the stages of formation of element-centered radicals and their reaction with the oxygen generated by the system. The intermediate organometallic peroxides can also acts as oxidants for the element (Si, Ge)-hydrogen bonds.
三烷基(芳基)硅烷和锗烷在温和条件下(室温,苯或四氯化碳中)主要通过元素-氢键有效地与金属(铝、钛)叔丁醇-叔丁基过氧化氢反应。产物的特性取决于元素的性质、与其结合的基团结构以及溶剂。该过程本质上是自由基的。它包括元素中心自由基的形成阶段及其与体系产生的氧的反应。中间体有机金属过氧化物也可以作为元素(硅、锗)-氢键的氧化剂。
