A synthetic approach to beta-(chloromethyl)furans with free 2 and 5 positions is developed. It is shown that these compounds enter the Michaelis-Becker reaction to form usual phosphorylation products. With 3,4-bis(diethoxyphosphorylmethyl)furan, two conformers with different chemical shifts of phosphorus nuclei and PCH2 protons were detected.
hyl groups in the furan ring have been synthesized via the Arbuzov reaction from the corresponding acid chlorides. NMR spectral parameters of the prepared compounds were studied. The values of coupling constants between the phosphorus nuclei and the carbon nuclei of the furan ring have been examined with relation to the location of the acylphosphoryl group in the furan ring, the nature of second substituent
