[Figure not available: see fulltext.] The reaction of 3,6-bis(het)aryl-1,2,4-triazines (hetaryl ≠ 2-pyridyl) with aryne intermediates generated in situ was studied. As a result, novel 1,4-bis(het)arylisoquinolines were synthesized with yields of up to 45%. The main rules of the reactions were studied, and the obtained experimental data were compared with those described in the literature.

The scope of functionalization of 1,2,4-triazines can be considerably extended via successive nucleophilic substitution of hydrogen (S NH) and ipso-substitution. A convenient procedure has been developed for direct cyanation of 1,2,4-triazine 4-oxides with acetone cyanohydrin in the presence of triethylamine. The cyano group in the resulting 5-cyano-1,2,4-triazines is readily replaced by reactions with various aliphatic alcohols and amines.

Dehydroxy-chlorination of 6-methyl-3-phenyl (3a), and 3,6-diphenyl-5-oxo-2,5-dihydro-1,2,4-triazine (3b) afforded the corresponding 5-chloro-1,2,4-triazines (4a,b).The chloro-1,2,4-triazines (4a,b) treated with sodium alkoxides or amines to give the 5-alk
