The synthesis of 1, 2-disilylethanes [R1R2R3Si (CH2) 2SiR1R2R3] is usually conducted by using noble metal reagents or catalysts. This work describes a new electrochemical synthetic method for their preparation in good yields by oxidation of α-silylacetic acids at Pt anodes (Kolbe electrolysis). Most of the reported synthesized 1, 2-disilylethanes in this work are unknown.
