The interaction between the fluorinated alcohols RFOH (R F = (CF3)~CH and (CF3)3C) and rhenium hydride (qS-CsMes)ReH(CO)(NO) in hexane and liquid freon was studied in a wide temperature range by IR and IH NMR methods, respectively. The formation of hydrogen-bonded complexes of two types, ReH...HOR r: and NO...HOR F, was established. The hydride signal in the IH NMR spectra at 96 K splits into two signals (at 6 = -7.54 and -8.87) corresponding to the free ReH and the ReH...HO complex, respectively.When boiled in aromatic hydrocarbons, solutions of ct-nitro-a-azinylcyanoacetic esters of the pyrimidine, pyrazine, and s-triazine series gave the corresponding a-hydroxy derivatives of ct-azinylcyanoacetic esters in high yields.Previously, we have demonstrated that nitration of dihydroazinylidenecyanoacetic esters of the pyrimidine series, la--d, I and of the pyrazine series, le, z afforded c~-hydroxy derivatives of ct-azinylcyanoacetic esters 3a--e in low yields along with a-nitro derivatives 2a--e.
