Palladium(II) catalysed silicon-oxygen bond formation versus rearrangement reactions

Article abstract of DOI:10.1080/10426500108546578

Phenylsilane and diphenylsilane undergoes rearrangement reactions by palladium catalysts such as Pd(TMEDA)Cl₂, Pd(TEEDA)Cl₂, [Pd(PPh₃)]₂Cl₂ (where TMEDA = tetramethylethylenediamine, TEEDA = tetraethylethylenediamine) at room temperature. However, the reductive Si-O bond forming reaction can be performed on hydrosilanes through competitive paths. The reactions of phenylsilane and quinonic compounds are catlaysed by Pd(TMEDA)Cl₂ (such as 1,4-benzoquinone, 1,4-napthoquinone) to give siloxanes, backbone of these siloxanes which contains rearranged phenylsilane units. The thin films of such oligomers has plot of resistance vs temperature profile resembling semiconductor.
