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
