Dihalocyclopropanation of Phenylthio or Butylthiocycloalkenes Under Phase Transfer Conditions. Opening of Cyclopropanes Under Microwave Irradiation
摘要:
Dihalocarbenes (X=Cl,Br) generated under phase transfer conditions added to phenylthio or butylthiocylcloalkenes give corresponding 1,1-dihalo-2-thiobutyl or thiophenyl-cyclopropanes. The ring opening of dichlorophenylthiocyclopropanes (2a, 2b, 2c) was obtained by using silver tetrafluoborate on alumina under microwave irradiation.
