methyllithium in the presence of ethyl vinyl ether. A cyclopropane derivative was not obtained from the reaction of 9,9-dibromofluorene (III) or 9,9-dichloro-9H-tribenzo[a.c.e]cycloheptene (IV) with alkyllithium in olefin but 9,9′-bifluorenylidene (IX) and 9,9′-dibromo-9,9′-bifluorenyl (XI) were produced from III and 9-methylene-9H-tribenzo[a.c.e]cycloheptene (XXIII) and 9H-tribenzo-[a.c.e]-cyclohepten-9-ol
在乙基乙烯基醚的存在下,由二溴二苯基甲烷(II)与甲基锂的反应获得1,1-二苯基-2-乙氧基环丙烷。由9,9-二溴芴(III)或9,9-二氯-9 H-三苯并[ace]环庚烯(IV)与烷基锂在烯烃中的反应未得到环丙烷衍生物,但9,9'-联芴基(IX) III和9-亚甲基-9 H-三苯并[ace]环庚烯(XXIII)和9 H-三苯并-[ace] -cyclohepten -9生成9,9'-二溴-9,9'-联芴基(XI)IV的-ol(XXIV)。讨论了反应机理。
