[1,3,4]Thiadiazolo[2,3-c][1,2,4]triazines was written by Gakhar, H. K.;Prabha, Usha;Gill, J. K.. And the article was included in Journal of the Indian Chemical Society in 1984.Product Details of 57179-35-8 This article mentions the following:
The cyclocondensation of aminotriazinethiones I (R = Me, Ph) with R1CHO [R1 = Ph, O2NC6H4, (un)substituted 3,4-(methylenedioxy)phenyl, HO(MeO)C6H3] gave thiadiazolotriazines II. I (R = Me) in ether was treated with HCl gas, the ether was decanted, the residue was placed in EtOH, PhCHO and NaOAc were added, and the mixture was refluxed to give II (R = Me, R1 = Ph). In the experiment, the researchers used many compounds, for example, 3-Hydroxy-5-methoxybenzaldehyde (cas: 57179-35-8Product Details of 57179-35-8).
3-Hydroxy-5-methoxybenzaldehyde (cas: 57179-35-8) belongs to ethers. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive. Electron-deficient reagents are also stabilized by ethers. For example, borane (BH3) is a useful reagent for making alcohols. Pure borane exists as its dimer, diborane (B2H6), a toxic gas that is inconvenient and hazardous to use. Borane forms stable complexes with ethers, however, and it is often supplied and used as its liquid complex with tetrahydrofuran (THF).Product Details of 57179-35-8
