A convenient procedure has been developed for the preparation of Group14 compounds by integrated palladium‐catalyzed cross‐coupling of aromatic iodides with the corresponding Group14hydrides in the presence of a base. The reaction conditions can be applied to the cross‐coupling of tertiary, secondary, and primary Group14 compounds. In most cases, the desired arylated products were obtained in synthetically
Monohydrosilanes can be prepared selectively in high yields from the reaction of various aryl and alkyl iodides with ytterbium metal followed by the reaction with dihydrosilanes.

An efficient electrochemical radical silyl‐oxygenation of electron‐deficient alkenes is demonstrated, which gives access to a variety of new highly functionalized silicon‐containing molecules, including β‐silyl‐cyanohydrin derivatives in good yields with excellent chemo‐ and regio‐selectivity. This electrochemical radical silylation process conducts under mild conditions without the use of transition
The photocatalyzed synthesis of silanols from tertiary silanes has been carried out using eosin Y under air. This is a metal-free method that uses a low catalyst loading, atmospheric oxygen as the oxidant, and visible-light conditions (blue light).
使用曙红 Y 在空气中进行了由叔硅烷光催化合成硅烷醇。这是一种无金属方法,使用低催化剂负载、大气中的氧气作为氧化剂和可见光条件(蓝光)。
