of a bimolecular (1d* + 1d) step. The structure of 7d was established by spectroscopy and by its hydrolysis to 3-cyclohexyl-4,4,6,6-tetramethyl-2-cyclohexenone (8). The previously made assumption that N-(2-cyclohexen-1-ylidene)cyclohexylamine (1a) and 2,3,4,4a,5,6-hexahydroquinolines 2 photorearrange to N-cyclohexylidenecyclohexanamine 3a and 3,4,4a,5,6,8a-hexahydroquinolines 4, respectively, via a light-induced
N-(4,4,6,6-四甲基-2-环己烯-1-基)-1,1,3,3-四甲基-2-环己烯-1-基-1的辐照(λ= 254 nm), 1,3,3-四甲基丁胺(7d)依次由相同波长的光进行光分解,但速率比形成的慢四倍。光产物7d的形成速率是起始原料1d浓度的函数,表明涉及双分子(1d * + 1d)步骤。7d的结构通过光谱学和水解为3-环己基-4,4,6,6-四甲基-2-环己烯酮来确定(8)。先前的假设是N-(2-环己烯-1-基)环己胺(1a)和2,3,4,4a,5,6-六氢喹啉2与N-环己叉基环己胺3a和3,4,4a,5,6,8a-六氢喹啉4重排分别通过光诱导的1,3-氢位移证明是不正确的。
