The title compound, C(19)H(17)ClN(4), was obtained from the reaction of 3-chloro-5,6-diphenyl-1,2,4-triazine with isobutyronitrile in the presence of lithium diisopropyl-amide as an unexpected product of covalent addition of isobutyronitrile carbanion to the C-5 atom of the 1,2,4-triazine ring. The 2,5-dihydro-1,2,4-triazine ring is essentially planar (r.m.s. deviation = 0.0059 Å) and the 5- an...
متن کاملRing Cleavage of Some Bicylic Compounds Derived from 1,2,4-Triazine
Ring cleavage occurred when 1,2,4-triazino-1,2,4-triazines (3), (4) and (5) were treated with concentrated hydrochloric acid to yield N-substituted triazines (7) and (8). These confirm the given configuration assigned to the isomeric triazinotriazines. 6-Methyl-2-phenyl-7H-oxazolo [3,2-b][1,2,4]-triazin-7-one (9) underwent ring cleavage on treatment with sodium alkoxide to afford 3-alkoxy-1...

The 1,2,4-triazine ring in the title compound, C(14)H(15)N(3)O(3), is approximately planar (r.m.s. deviation = 0.019 Å); the C atom at the 6-position deviates by 0.026 (2) Å from the mean plane whereas the C atom at the 2-position deviates by 0.166 (4) Å in the opposite direction. The triazine ring is oriented at 8.60 (13)° with respect to the phenyl ring. The imino group is hydrogen-bond donor...
