Approach was developed underlain by the use of fluorinated diazocompounds to the synthesis of derivatives of alpha-trifluoromethyl-alpha-hydroxycarboxylic acids and their phosphorus-containing analogs, alpha-trifluoromethyl-alpha-hydroxyphosphonic acids. Methyl 2-diazo-3,3,3-trifluoropropionate and diethyl 1-diazo-2,2,2-trifluoroethylphosphonate under the action of catalytic quantities of dirhodium tetraacetate Rh-2(OAc)(4) easily inserted into the O-H bond leading to the formation of the corresponding products in high yields.
