摘要：
Hydrolysis of trialkoxysilanes having various substituents gave cyclic tetrasiloxanetetraols with all-cis isomer as the major fraction in the presence of equimolar amounts of water and sodium hydroxide. All stereoisomers of phenyl derivative were produced by isomerization of the all-cis isomer in the presence of hydrochloric acid, and isolated and identified.
