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

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
