Rates of reaction of benzylamines with 1-chloro 2.4-dinitrobenzene
, 1963 Several meta and para substituted benzylamines have been prepared. The rates of reaction of benzylamine and fourteen substituted benzylamines with 1-chloro 2,4-dinitrobenzene in ethanol have been measured. The kinetics were followed by using an acid-base

Bulletin of the Korean Chemical Society, EarlyView.Abstract DNA‐encoded libraries (DELs) enable large‐scale screening for hit identification, but accessing sp3‐rich, three‐dimensional chemotypes beyond flat, aromatic scaffolds remains challenging. Multicomponent reactions (MCRs) assemble such complexity from simple building blocks in a single step, and reaction‐engineering strategies have extended on ...
