Microwave-assisted synthesis of 4-amino-3-[2-benzo[b]furyl]-5-mercapto-1,2,4-triazole and its derivatives was written by Wang, Xi-Cun;Quan, Zheng-Jun;Li, Zheng. And the article was included in Youji Huaxue in 2005.Electric Literature of C9H10O4 This article mentions the following:
4-Amino-3-(2-benzofuryl)-5-mercapto-1,2,4-triazole was synthesized by the reactions of 2-benzo[b]furoyl hydrazine with CS2 and next hydrazine under microwave irradiation Treatment of the resulting 4-amino-5-mercapto-1,2,4-triazole with aromatic carboxylic acids (or aryloxyacetic acids), α-bromoacetophenones and aromatic aldehydes under microwave irradiation yielded the corresponding 1,2,4-triazolo[3,4-b]-1,3,4-thiadiazoles, 1,2,4-triazolo[3,4-b]-1,3,4-thiadiazines and 4-arylideneamino-5-mercapto-1,2,4-triazole in good to moderate yields, resp. The structures of all these new compounds were confirmed by elemental analyses, IR, 1H NMR and MS spectra. In the experiment, the researchers used many compounds, for example, 2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4Electric Literature of C9H10O4).
2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. Ethyl ether is an excellent solvent for extractions and for a wide variety of chemical reactions. It is also used as a volatile starting fluid for diesel engines and gasoline engines in cold weather. Dimethyl ether is used as a spray propellant and refrigerant. Methyl t-butyl ether (MTBE) is a gasoline additive that boosts the octane number and reduces the amount of nitrogen-oxide pollutants in the exhaust. The ethers of ethylene glycol are used as solvents and plasticizers.Electric Literature of C9H10O4
