Results of low-temperature (130 K) crystal structure analyses for seven β-trimethylsilyl-substituted cyclohexylnitrobenzoate esters are reported.For those molecules (three) with the Si-C and C-O bonds antiperiplanar the C-O bond lengths are increased by 0

Epoxide ring-opening of 1,2-epoxy-1-trimethylsilylcyclohexane (3) has given a range of the 2-substituted 2-trimethylsilylcyclohexanols (4; X = H, OH, OMe, OCH2CH=CH2, Br, I, SCN) in which attack by nucleophile has occured at the carbon α to silicon.The products (4) have been transformed into a number of functionalised silanes, including the silyl-episulphide (9).Other epoxides which have been less extensively studied are the conformationally biased epoxysilanes (10) and (11), the eight-membered ring epoxysilanes (17) and (21) and the two stereoisomeric 2,3-epoxy-3-trimethylsilylpentanes (26) and (29).Epoxide ring-opening adducts were obtained after treatment with H+-MeOH in all cases except for compound (17), where the bicyclic alcohol (18) was formed by a transannular reaction.
