Abstract: | The Michaelis-Arbuzov reactions of BrCH2COCMe3 or 3-(substituted vinyl)-2,2-dimethylcyclopropanecarbonyl chlorides with phosphites (RO)2P(OR') afford (RO)2P(O)CH2COCMe3 (e.g., R = Me, Et, Bu) in 25.3-81.9% yield and (RO)2P(O)COCH2CH[C(:CH2)Me]CH:CX2 (e.g., R = Me, X = Me or Br) in 42.1-81.4% yield., resp. Bromination (Br2, NaOAc, AcOH) of (RO)2P(O)CH2COCMe3 afforded (RO)2P(O)CHBrCOCMe3 in 40.1-66.1% yield. The phosphonates (EtO)(iPrNH)P(O)CH2COCMe3 and (MeO)(Et2N)P(O)CH2COCMe3 were also prepared |
