The course of the reaction between N-methylmorpholine-N-oxide 290 (NMMO) and cyanuric chloride is strictly dependent on the hydrate water content of the amine oxide (Scheme 55). The reaction can be conducted in such a way that a clean deoxygenative demethylation is achieved <2002T9809>. Sig...
were dissolved in DCM (10–30 mL) and triethylamine (2 eq. for free amine, 4 eq. for tosylate salt) was added. The reaction mixture was stirred at room temperature for 22–48 h while monitored by TLC. Additional DCM or chloroform (10–20 mL) was added and the solution washed with ...
16 Imidoyl chlorides react with alcohols or phenols in the presence of base (alkoxide, tertiary amine) to give imidates, e.g. (235; equation 127).3,364,370,468–474 This method is especially useful for the preparation of arylimidates; the reaction can be performed under phase transfer ...
also react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Their reaction with carbonates and bicarbonates generates a harmless gas (carbon dioxide) but still heat. Like other organic compounds, carboxylic acid...
Nitrous acid then partakes in diazotization with a primary aromatic amine on an advanced intermediate to form the N–N bond in a reaction catalyzed by CreM, a fatty acid-coenzyme A ligase homolog (Supplementary Fig. 1c)9,10. Recently, we reported that the fosfazinomycin biosynthetic ...
To study the reactivity of the sulfonamide radical in various reaction systems, the photodecomposition of N-t-butyl and N-methyl-N-chloroalkanesulfonamides was investigated. In benzene, the competitive hydrogen abstraction by the chlorine atom occurred to an appreciable extent and the participation of...
phenol and liquid caustic soda are produced into solution of the sodium salt of phenol, vacuum drying, and then to 100℃, slowly put to the dry carbon dioxide, when the pressure reaches 0.7~0.8MPa, stop passing carbon dioxide, warming up to 140 to 180℃. After the reaction with water, ...
Sulfamic acid is a solid strong acid that esterifies with the hydroxyl group on polysaccharides, thus introducing sulfonic groups to the polysaccharide molecular chain. The reaction between polysaccharide and sulfamic acid to form sulfonated polysaccharides is shown in Fig. 2. In brief, polysaccharide...
