The synthesis of 1,1-diphenyl-1-germacyclopent-2-ene from its β-ethylenic isomer is described. 6-Oxa-2,2-diphenyl-2-germabicyclo[3.1.0]hexane, prepared by oxidation of the α-ethylenic ring with peracid, leads, by thermal rearrangement, to a mixture of 1-oxa-2-germacyclohex-5-ene and 1-germacyclopentan-3-one. 1,1-Diphenyl-1-germacyclopentan-2-ol, synthesised by hydroboration—oxidation from the germacyclopent-2-ene
描述了由其β-烯键式异构体合成1,1-二苯基-1-锗环戊-2-烯。通过用过酸氧化α-烯键环制得的6-Oxa-2,2-二苯基-2-germabicyclocyclo [3.1.0]己烷通过热重排导致生成1-oxa-2-germacyclohex-的混合物5-烯和1-germacyclopentan-3-one。通过氢硼化-从萌芽环戊-2-烯氧化而合成的1,1-二苯基-1-germacyclopentan-2-ol经1-oxa-2,2-diphenyl-2-germacyclo己烷钠和4-diphenylhydrogermylbutan-处理1-ol。将有机锗环记录的结果与同源硅衍生物进行比较。
