Photolysis of a series of silyl ketones with the general structure (CH3)3Si(CH2)nCOR with n = 0–4, R = C6H5 and with n = 0–3, R = CH3 has been investigated. When n = 3 or 4 a major course of reaction is the Type II cleavage. When R = CH3 and n = 3 a substantial amount of cyclobutanol formation occurs; none is detected when R = C6H5. If n = 2 and R = C6H5 the only photoreactions established are reductive
具有通式结构的一系列甲硅烷基酮的光解(CH 3)3 SI(CH 2)ñ COR与Ñ = 0-4,R = C 6 H ^ 5,并用Ñ = 0-3,R = CH 3已经调查。当n = 3或4时,反应的主要过程是II型裂解。当R = CH 3且n = 3时,会形成大量的环丁醇。当R = C 6 H 5时,没有检测到。如果n = 2且R = C 6 H 5唯一建立的光反应是还原性烷基化(通过溶剂环己烷)和羰基亚甲基键的裂解。如果R = CH 3,则可以在羰基-亚甲基键的初始裂解的基础上使所有分离出的产物合理化。在惰性溶剂中,n = 1或0的化合物几乎不会发生光化学分解。但是,每种化合物都容易进行光催化水解以形成三甲基硅烷醇和醛或酮。
