Methylation of the l,2-dihydro-2-hydroxy pseudo base (90) with trimethyloxonium hexa-fluorophosphate led to the formation of the 1-methyl derivative (91) (Equation (10)) <92T8459>. Compound (92) was cyclized on treatment with polyphosphoric acid to the furo[2,3-e]pyrido[l,2- ][1.2,4]triazinium salt (93) (Equation (11)) <89CB1935>, which proved to be a versatile starting material for 2-methoxy- and 2-pyrrolidinopyrido[l,2-h][l,2,4]triazines <89CB1935>, and also for pyridazino-fused derivatives <90CB1415>.

NMR analysis. The spectra are recorded by a Varian DA-60-IL spectrometer. Deuterated dimethylformamide (DMF-d7) has been used as solvent. The copolymer solutions (10%) are heated at 130°C (internal reference Hexa-methyl-di-siloxane (HMDS), hmds = 0.05 ppm). Enhanced signal/noise ratios have been achieved by the Jeol-JR-Al Spectrum Accumulator and the decompositions and simulations of the complex pattern of methoxy and a-methyl resonances, by the Du Pont de Nemours, 310 Curve Resolver. Lorentzian curves, with a line width at half height of 2 Hz, have been used to simulate all the complex pattern of the methoxy and a-methyl resonances. The line width value has been determined from experimental measurements on NMR spectra. The broadening of the two a-methyl singlets from the s and h triad sequences are probably due to pentad effects [2, 5].

Results of a preliminary electron-diffraction study of hexafluorobicyclo-[2,2,0]hexa-2,5-diene (111) have been reported. Its F n.m.r. spectrum has been fully analysed, and those of several of its derivatives have been studied,as have the kmetics of thermal re-aromatization of some of its incompletely characterised methyl-, trifluoromethyl-, methoxy-, and H-substituted derivatives. ...
