不饱和烯醇硅基醚在电子转移敏化剂9,10-二氰蒽存在下辐照形成硅氧基阳离子，其有效地环化生成环酮。不饱和烯醇硅基醚的环化反应只能生成6元环。
Unsaturated enol silyl ethers are irradiated in the presence of the electron transfer sensitizer 9,10-dicyanoanthracene to form silyloxy radical cations which cyclize efficiently to yield cyclic ketones. Cyclization reactions of epsilon,zeta-unsaturated enol silyl ethers lead exclusively to 6-membered rings.
