Description
1,1,2,2-Tetramethyl-1,2-diphenyldisilane features a sterically shielded Si–Si bond flanked by phenyl and methyl groups, enhancing stability under ambient conditions. This disilane integrates readily into hydrosilylation reactions, serving as a robust silicon source for functionalized silanes and siloxanes in polymer synthesis and surface modification applications.
Application
1,1,2,2-Tetramethyl-1,2-diphenyldisilane serves as a stable, bench-ready silane reagent enabling efficient hydrosilylation and cross-coupling transformations. Its tetramethyl substitution enhances air stability and simplifies purification, while the diphenylsilane core facilitates reliable Si–H bond transfer in catalytic processes. Functions effectively in transition-metal-catalyzed coupling protocols and as a building block for functionalized silanes in synthetic organic chemistry.
