Pyrolysis (fvp) of a strained γ-sultine (3) produced 1H-indene-1-carboxaldehyde (8) and naphthalene. The key step in the production of aldehyde (8) involves a 1,3-dipolar cycloreversion, as evidenced by the trapping of an intermediate sulfene (6) with methyl acrylate. A diradical pathway is proposed for the formation of naphthalene.
应变的γ-磺胺(3)的热解(fvp)产生了1H-茚-1-甲醛(8)和萘。醛(8)生产中的关键步骤涉及1,3-偶极环还原,这是通过用丙烯酸甲酯捕获中间亚砜(6)来证明的。提出了形成自由基的双自由基途径。
