Synthese von 1,2-Bis(silyl)indolen unter anionischer 1,2-Silatropie
摘要:
Under the influence of n-butyllithium, 1-(tert-butyldimethylsilyl)indole (1) submits to an 1,2-silatropie giving the 2-(tert-butyldimethylsilyl)indole (2). Treating 2 with n-butyllithium and fluoro- or chlorosilane leads to 1,2-bis(silyl)indoles (3,4). 1 was characterized by crystal structure and 2 by complete C-13-NMR analyses in solution.
