Synthesen stickstoffhaltiger Heterocyclen, XXIX. Über 1.2.4‐Triazine, III

Abstract

Die Darstellung eines s‐Triazolo[3.4‐c]‐as‐triazins (III), zweier Tetrazolo[5.4‐c]‐as‐triazine (IV, V) und eines as‐Triazino[4.3‐b]‐as‐triazins (IX) wird beschrieben.

The Chemistry of Hydrazonates

“…As expected, cyclization of the hydrazonates 244, having N-2 blocked 1,2,4-triazine residue was reported to give the respective 1,2,4-triazolo [3,4-c] [1,2,4]triazine derivatives 245 [148].…”

Syntheses of New Sulfur−Nitrogen Palladacycles − Crystal Structures of [(AMTTO)PdBr2]2·3.5THF, [(AMTTO)PdI2]2·3MeOH, [(AMTTO)Pd(PPh3)Br]Br·MeOH, and [(AMTTO)Pd(PPh3)I]·2MeOH (AMTTO = 4-Amino-6-methyl-1,2,4-triazine-3-thione-5-one)

“…Mesomeric forms of the anionic AMTTO ligand Compounds 2؊5 were found to be air-stable crystalline solids. The 13 C NMR spectrum of the ligand AMTTO has been published for the Ag complex [Ag(AMTTO) 2 ]NO 3 [2] and the data are almost unchanged in the spectra of 2؊5. The 31 P NMR spectra of 4 and 5 feature only one sharp singlet at δ ϭ 30.3 and δ ϭ 26.2, respectively, in accordance with the geometries of these compounds.…”

“…General Remarks: AMTTO [13] and 1 [3] were prepared according to literature procedures. Ϫ IR spectra were recorded on a PerkinϪElmer spectrometer 883 (KBr pellets, Nujol mulls, 4000Ϫ250 cm Ϫ1 ) or on a Bruker IFS 88 instrument (CsBr discs, 4000Ϫ400 cm Ϫ1 ; polyethylene discs, 500Ϫ100 cm Ϫ1 ; Nujol mulls).…”
