Zusammenfassung, Abstract
The reaction of the nitroxy radical 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO) with SiCl4 has been investigated in detail. One silicon-contg. product, TEMPO-SiCl3 (1), could be isolated in cryst. form, and its crystal structure was detd. The structural parameters have been compared with the related hydroxylaminotrichlorosilane known from the literature and with DFT calcns. According to the calcns., the formation of 1 follows an SN2 mechanism, which is thermodynamically favored over an SN1 pathway. Upon hydrolysis, 1 decomps. and yields several TEMPO-contg. species. These were all characterized crystallog. [on SciFinder(R)]
