Forsyth, Craig M. published the artcileN,N-Dialkyl-N’-Chlorosulfonyl Chloroformamidines in Heterocyclic Synthesis. Part IX. Novel Triazolo-Fused Thiatriazoles and Pyrazolo-Fused Oxathiazines, Safety of 1-(2-Chlorophenyl)-3-methyl-5-pyrazolone, the publication is Australian Journal of Chemistry (2010), 63(5), 785-791, database is CAplus.
[1,2,4]Triazolo[1,2-b][1,2,3,5]thiatriazole derivatives were obtained by a reaction of N,N-dialkyl-N’-chlorosulfonyl chloroformamidine derivatives with 4-substituted urazoles in a selective 1,2-NN-dinucleophilic mode of action. A reaction of the above-mentioned N,N-dialkyl-N’-chlorosulfonyl chloroformamidine derivatives with N1-substituted 5-pyrazolones afforded pyrazolo[4,3-e][1,4,3]oxathiazine derivatives by a selective 1,3-CCO dinucleophilic substitution. [1,2,4]Triazolo[1,2-b][1,2,3,5]thiatriazole derivatives and pyrazolo[4,3-e][1,4,3]oxathiazine derivatives were the only products isolated from the resp. reactions and both represent new ring systems.
Australian Journal of Chemistry published new progress about 14580-22-4. 14580-22-4 belongs to pyrazoles-derivatives, auxiliary class Organic Pigment, name is 1-(2-Chlorophenyl)-3-methyl-5-pyrazolone, and the molecular formula is C10H9ClN2O, Safety of 1-(2-Chlorophenyl)-3-methyl-5-pyrazolone.
