Heteroaromatic oxidation pyrazine

Paudler and Jovanovic attempted the classification between 7t-excessive and Ti-deficient heteroaromatics by a quantitative measure defined from the C NMR chemical shifts <820MR(19)192>. They also examined back donation in pyrazine A -oxides based on the interrelationships between N, C chemical shifts and IR absorption frequencies <82H(19)93>. [Pg.238]
