- Rapid and efficient copper-catalyzed finkelstein reaction of (hetero)aromatics under continuous-flow conditions
-
A general, rapid, and efficient method for the copper-catalyzed Finkelstein reaction of (hetero)aromatics has been developed using continuous flow to generate a variety of aryl iodides. The described method can tolerate a broad spectrum of functional groups, including N-H and O-H groups. Additionally, in lieu of isolation, the aryl iodide solutions were used in two distinct multistep continuous-flow processes (amidation and Mg-I exchange/nucleophilic addition) to demonstrate the flexibility of this method.

Trimethylsatannyl and bis(trimethylstannyl) derivatives of pyridine, quinoline, and isoquinoline were prepared from the corresponding halo and dihalo (chloro or bromo) derivatives and trimethylstannyl sodium, which was generated in situ from chlorotrimethylsatannane and sodium.These stannyl derivatives readily underwent iododestannation on treatment with iodine to produce the corresponding iodo and diiodo derivatives of pyridine, quinoline, and isoquinoline, respectively, in good yields.Keywords -trimethylsannylazine; bis(trimethylstannyl)azine; iodoazine; diiodoazine; iododestannation; trimethylstannyl sodium; chlorotrimethylstannane

Pyridines and quinolines bearing trimethylstannyl substituent at 2-, 3-, or 4-position were synthesized by the reaction of the respective chloro or bromo derivatives with trimethylstannyl sodium, generated in situ from chlorotrimethylstannane and sodium, in the range of 61-88percent yields.Upon treatment with iodine, these trimethylstannyl derivatives smoothly underwent iododemetallation to give the corresponding iodo derivatives of pyridine and quinoline in satisfactory yields.
