The first electrochemical hydrolysis of hydrosilanes to silanols under mild and neutral reaction conditions is reported. The practical protocol employs commercially available and cheap NHPI as a hydrogen‐atom transfer (HAT) mediator and operates at room temperature with high selectivity, leading to various valuable silanols in moderate to good yields. Notably, this electrochemical method exhibits a

oxidant at an iron catalyst loading of 0.1 mol % is reported. The practical and highlyselective oxidation exhibits good functional group tolerance, allowing effective access to diverselyfunctionalized alkyl-, aryl-, alkynyl-, and alkoxysilanols, silanediols, as well as mono-, oligo-, and polymeric siloxanols with various substituent patterns. Late-stage gram-scale application in functional-molecule-containing

Herein, a four-coordinated organoboron compound, aminoquinoline diarylboron (AQDAB), is utilized as the photocatalyst in the oxidation of silane to silanol. This strategy effectively oxidizes Si–H bonds, affording Si–O bonds. Generally, the corresponding silanols can be obtained in moderate to good yields at room temperature under oxygen atmospheres, representing a green protocol to complement the

electrochemical approaches for NaCl-mediated hydrolysis of hydrosilanes have been well established to prepare silanols in moderate to good yields with good functional group tolerance under ambient conditions. Furthermore, electrochemical NaBr-promoted alcoholysis of hydrosilanes with a series of alcohols was successfully achieved under metal-free conditions. The synthetic application of eco-friendly
