An efficient solvent-less procedure has been expanded to synthesis primary amides through Beckman rearrangement using Cu(II)/hydroxyl terminated triazine-based dendrimer (Cu(II)/TD) as a proficient heterogeneous nano-catalyst. The Cu(II)/TD nano-catalyst was recognized using TEM, FT-IR, TGA, SEM, EDS, XRD and ICP techniques. The deploying of this new nano-catalyst provides the synthesis of assorted primary amides in outstanding yields through a simple working-up method in a short-term reaction under green conditions in the absence of dangerous and poisonous organic solvents. The Cu(II)/TD catalyst was able to reprocessed and recovered many times without considerable failure of its performance. In the experiment, the researchers used many compounds, for example, 3,4-Dichlorobenzamide (cas: 2670-38-4Product Details of 2670-38-4).
3,4-Dichlorobenzamide (cas: 2670-38-4) belongs to amides. In primary and secondary amides, the presence of N–H dipoles allows amides to function as H-bond donors as well. Thus amides can participate in hydrogen bonding with water and other protic solvents; the oxygen atom can accept hydrogen bonds from water and the N–H hydrogen atoms can donate H-bonds. As a result of interactions such as these, the water solubility of amides is greater than that of corresponding hydrocarbons. These hydrogen bonds are also have an important role in the secondary structure of proteins.Product Details of 2670-38-4
