The acylation of both aliphatic and aromatic amines, alcs. and amino alcs. by simultaneous IR-ultrasound irradiation (SIUI) in solvent-free conditions in short reaction times and with good to excellent yields was achieved. The results obtained with SIUI and for thermal, IR and ultrasound energy sources are compared. This is the first report regarding to the application of SIUI in acylation reactions. In the part of experimental materials, we found many familiar compounds, such as 2,2-Dimehtyl-N-pyridin-3-yl-propionamide(cas: 70298-88-3Product Details of 70298-88-3)
2,2-Dimehtyl-N-pyridin-3-yl-propionamide(cas: 70298-88-3) belongs to anime. Acylation is one of the most important reactions of primary and secondary amines; a hydrogen atom is replaced by an acyl group (a group derived from an acid, such as RCOOH or RSO3H, by removal of ―OH, such as RC(=O)―, RS(O)2―, and so on). Reagents may be acid chlorides (RCOC1, RSO2C1), anhydrides ((RCO)2O), or even esters (RCOOR′); the products are amides of the corresponding acids.Product Details of 70298-88-3
