tosylate (IX) in unbuffered medium at 65° yields as results of a multistep process a nonolefinic hydrocarbon which turned out to be tetrahydroperinaphthane (XII). However, formolysis in the presence of sodium formate leads with ring enlargement to 1:2-benzocyclononenyl-(4)-formate (XX) and 1:2-benzocyclonona-1,3-diene (XXII). Also the hydrolysis of IX is accompanied by complete rearrangement to XIX
在多步法的结果下,在无缓冲介质中,将1:2-苯并环辛烯基-(3)-甲苯磺酸甲酯(IX)进行多步法转化为非烯烃,结果证明是四氢环萘烷(XII)。但是,在甲酸钠存在下进行甲酸分解会导致环扩大为1:2-苯并环壬烯基-(4)-甲酸酯(XX)和1:2-苯并环壬基-1,3-二烯(XXII)。IX的水解还伴随着对XIX和XXII的完全重排。讨论了四氢过环庚烷的形成机理。
