Application of 2568-33-4, Adding some certain compound to certain chemical reactions, such as: 2568-33-4, name is 3-Methylbutane-1,3-diol,molecular formula is C5H12O2, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 2568-33-4.
General procedure: In the Schlenk reaction vessel,Methyltri n-octylphosphonium methyl carbonate([Me (n-octyl) 3P] + [OCO2Me]-,Charge the catalyst (C1a), 55.8 muL, 0.12 mmol),Methyl methacrylate (MMA, 4 mL) was added and stirred at room temperature for 1 to 2 minutes. Then, 3-methylbutane-1,3-diol (compound (3a), 21 3 muL, 2.0 mmol), internal standard substance (4,4′-di-tert-butylbiphenyl, 53.3 mg, 0.20 mmol), 1.0 g of dried powdery molecular sieves 5A (MS 5A) was added, and the mixture was stirred at room temperature (25 C.) for 3 hours to carry out an ester exchange reaction represented by the following formula. During the reaction, the progress of the reaction was confirmed by thin layer chromatography (TLC) as appropriate. The reaction mixture was passed through a celite pad to remove MS 5A, MMA was distilled off from the mixture under reduced pressure, and after concentration, the yield of the reaction product was measured by 1H NMR (internal standard method). The concentrate was subjected to silica gel column chromatography (n-hexane: ethyl acetate = 50: 1 to 10: 1) to isolate a carboxylic acid monoester (compound (4a)). The yield and yield of the reaction product are shown in Table 1. In the reaction system, the reaction between the catalyst (C1a) and the alcohol derived from the raw material (compound (3a)) causes Me (n-octyl) 3P] + [OR5]-as a catalytically active species.(Most R5 is 3-hydroxy-3-methylbutyl).
According to the analysis of related databases, 2568-33-4, the application of this compound in the production field has become more and more popular.
