Nouvelles voies d'acces aux diaryl-3,6 hydroxy-5 triazines-1,2,4 a partir des nitriles α-thioethers
Pochat, Francis
, p. 3595 - 3596 (1981)
Ar-C(CN)=N-N=C(CN)-Ar and Ar-C(CN)=N-NH-CO-Ar', easily prepared from the bromoderivates Ar-CBr(SEt)-CN, afford in good yields, by heating in a basic medium, 3,6-diaryl-5 hydroxy-1,2,4-triazines.
