- Synthesis of trans-1,1-Dialkoxy-2,5-diphenyl-1-sila-3-cyclopentenes and Their 2-Alkyl Derivatives.
Description
The reaction of 1, 1-diethoxy or 1, 1-diisopropoxy-2, 5-dipheny1-1-sila-3-cyclopentene, containing cis and trans isomers, with LDA f ollowed by t he reaction with alkyl b romides (alky1=Et, n-Pr, i-Pr, iBu, s-Bu) and then acetic acid was investigated. The cis isomer of the 2, 5-diphenyl-1-sila-3-cyclopentene was selectively substituted by alkyl group to give 1, 1-dialkoxy-r-2-alkyl-2, t-5-diphenyl-1-sila3-cyclopentenes. The trans isomer of 2, 5-dipheny1-1-sila-3-cyclopentenes could be isolated by silica gel chromatography from the reaction mixture.
