[reaction: see text] Barton esters of beta-silylcarboxylic acids were decomposed by photolysis alone in organic solvents or in the presence of ethanesulfonyl azide or bromotrichloromethane. Products of the reaction, beta-silylthiopyridyl ethers, beta-silyl azides, or alkenes, were formed with significant control of stereochemistry.
[反应：见正文] β-硅基羧酸的巴顿酯在有机溶剂中单独光解，或在乙烷磺酰叠氮或溴三氯甲烷存在下光解。反应产物β-硅基硫代吡啶基醚、β-硅基叠氮化物或烯烃的形成具有显著的立体化学控制。
