focus on organics 3 active chloro-heterocycles active chloro-heterocycles heteroaromatic compounds in which a chlorine substituent is ortho or para to the nitrogen of an electron-deficient aromatic ring or is activated by the presence of an additional electron-withdrawing substituent are an extremely versatile class of building blocks in organic synthesis because of their propensity to undergo aromatic substitution when treated with classical nucleophiles for example 2-chloropyridine 1 x n is reportedly 230,000,000 times more reactive than chlorobenzene 1 x ch for the displacement of the chlorine by methoxide this activation occurs because ring nitrogens stabilize the dearomatised anionic intermediates meisenheimer complexes such as 2 which arise during the typical two-stage addition/elimination mechanism for such snar reactions naome 17312 meoh 42395 50c cl x ome x x n 11001 x ch 40449 x n 12610 x ch 15392 oxidative insertion of transition metals e.g pd into the activated
