WebJun 13, 2024 · [0002] Schiff bases are unique compounds having a C═N functional group, sometimes this bond referred to as an azomethine bond and possess the general formula R1 R2 C═NR3 (R3 not equal to H). Schiff bases are produced by condensing primary amines and carbonyl compounds (aldehyde & ketones). Ligands containing aryl substituents are … WebThere are various factors that affect the basicity of amines. For example, the presence of an electron-donating group increases the basicity of the amine, whereas the presence of an …
