low-temperature treatment of 1,1-dibromo-1a,9b-cyclopropa[l]phenanthrene with butyllithium appeared to produce dibenzonorcarynyliden(e/oid) which could be intercepted with phencyclone to produce a hindered spiropentane. The spiropentane readily rearranges, thermally and photochemically, into a triphenylene phenol derivative. The spiropentane and its rearrangement product were characterized by X-ray crystallography
用丁基锂低温处理 1,1-二溴-1a,9b-环丙[ l ]菲似乎会产生二苯并正亚芳基 (e/oid),它可以被苯环酮拦截,产生受阻螺戊烷。螺戊烷很容易通过热和光化学重排成苯并菲苯酚衍生物。通过X射线晶体学对螺戊烷及其重排产物进行了表征。
