Preparation and X-ray structure of cis-3-pentamethyldisilanylcyclohexyl p-nitrobenzoate
Green, Alison J.,White, Jonathan M.
, p. 27 - 30 (2007/10/03)
The title compound was prepared in three steps from cyclohex-2-enone. The C(alkyl)-O(ester) bond distance is 1·471(3) A which is not significantly different to that for other cyclohexyl p-nitrobenzoates. This suggests that the γ-pentamethyldisilanyl subst
