Abstract

The new reaction of alkylation of dicarboxylate phosphabetaines by alkyl halides in alcohol media has been opened. In this reaction alkyl radical enters to the ester part of molecule not from alkyl halide, but from the alcohol molecule. The structure of the isolated compounds was determined by IR and NMR spectroscopy, elemental and X-ray analysis.
