Arenecarbaldehydes ArCHO were allowed to react with a carbenoid reagent CF3CX2Mtl (X=Cl, Mtl=ZnCl, X=F, Mtl=LI) to give the adducts ArCH(OH)CX2CF3 whose hydroxyl group was substituted by fluorine.Dehydrohalogenating of the resultant ArCHFCX2CF3 (X=Cl or F
An Improved Synthesis of 1-Phenylpentafluoropropenes
Dmowski, Wojciech
, p. 25 - 30 (2007/10/02)
1-Phenylpentafluoropropene and a number of its para- and ortho-substituted derivatives were prepared in high yields by reaction of hexafluoropropene with etheral solutions of corresponding phenylmagnesium bromides in sealed glass tubes under autogenous pressure.The products were obtained as mixtures of the Z and E isomers, which ratios varied from 1/2 to 1/6 in favour of the E forms. 19F n.m.r. and i.r. spectra and b.p. of the 1-phenylpentafluoropropenes are reported.
