6,6-Bis(trimethylsilyl)norbornan-endo-2-ol (6) undergoes base-induced intramolecular displacement of a Si–Me group with formation of (9), in contrast to the monosilylated analogue (7).
A new series of tricyclononene derivatives with two and three silyl groups are successfully synthesized via [2 sigma+2 sigma+2 pi]-cycloaddition of silylethylenes to quadricyclane. The activity of the silylethylenes in the cycloaddition reactions was estimated. (C) 2011 Elsevier Ltd. All rights reserved.
