AI Article Synopsis
- Reinvestigation of Lewis acid catalyzed rearrangements in open-chain permethyloligosilanes revealed new fragmentation and cyclization reactions.
- Adding (trimethylsilyl)methyl groups to oligosilane substrates significantly enhanced the formation of cyclic or bicyclic carbacyclosilanes.
- Incorporating approximately 0.1% FeCl(3) into the AlCl(3) catalyst system improved its effectiveness.
Article Abstract
Reinvestigation of the Lewis acid catalyzed rearrangement of some open-chain permethyloligosilanes with the Al(Fe)Cl(3) catalyst system exhibited several cases of additional reactivity: namely, a fragmentation/cyclization reaction. Introduction of (trimethylsilyl)methyl substituents into the oligosilane substrates strongly facilitated this reaction, yielding cyclic or bicyclic carbacyclosilanes. Investigations concerning the composition of the catalyst system indicated that the incorporation of about 0.1% FeCl(3) into the AlCl(3) lattice provided an effective catalyst.
