In contrast to conventional stepwise synthesis of mol. Borromean rings, a self-assembly synthetic method which proceeds without the aid of a template was developed. In the formation of mol. rectangles, by adjustment of the long-arm length of the rectangles, size-dependent Borromean-link frameworks were constructed. Both the shortest length of two arms and the relative proportion of the length of the long arm to that of the short arm play a key role in the formation of Borromean rings. DFT calculations were used to provide theor. support for the formation of discrete interlocked frameworks. This study involved multiple reactions and reactants, such as N1,N2-Di(pyridin-4-yl)oxalamide (cas: 53118-43-7Recommanded Product: 53118-43-7).
N1,N2-Di(pyridin-4-yl)oxalamide (cas: 53118-43-7) belongs to amides. Amides include many other important biological compounds, as well as many drugs like paracetamol, penicillin and LSD. Low-molecular-weight amides, such as dimethylformamide, are common solvents. Amides are not in general accessible by the direct condensation of amines with carboxylic acids for two reasons: first, both components are readily deactivated by a transfer of a proton from the acid to the amine and second, the hydroxy unit on the carbonyl of the acid is a relatively poor leaving group. Nevertheless, the formation of five- and six-membered rings is often surprisingly simple provided that other factors can be brought into play to assist in the condensation.Recommanded Product: 53118-43-7
