Zn(tmp)2:: A versatile base for the selective functionalization of C-H bonds

Zn(tMP)(2) (tMP = 2,2,6,6-tetramethylpiperidinyl anion) is an effective base for the mild deprotonation of a broad range of substrates. Functionalized organozincs thus prepared are conveniently coupled with aryl bromides using typical Pd-catalyzed coupling methods.
