Category: chiral-catalyst. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 2-Chloroethyl acetate, is researched, Molecular C4H7ClO2, CAS is 542-58-5, about Synthesis of complex halo esters from α-chloromethyl esters of carboxylic acids. Author is Pishnamazzade, B.
