“…2-Fluoropyridine is metalated by sec-butyllithium or LITMP in tetrahydrofuran at 275 uC, after statistical correction, 720 or, respectively, 520 times faster than benzene. 85 At the same time the tendency of the substrate to undergo nucleophilic additions or substitutions increases steeply when a benzenic derivative is replaced by a pyridinic one. It requires skills and cleverly selected working conditions to manoeuvre successfully between the desired and undesired reaction mode.…”

“…The kinetics reflect such differences in thermodynamics. 2-Fluoropyridine is metalated by secbutyllithium or LITMP in tetrahydrofuran at -75 °C, after statistical correction, 720 or, respectively, 520 times faster than benzene [85] . At the same time the proneness of the substrate to undergo nucleophilic additions or substitutions increases steeply when a benzenic derivative is replaced by a pyridinic one.…”
