Solvent-controlled switch of selectivity between sp2 and sp3 C-H bond activation by platinum(II)

Solvent-controlled switch of selectivity between sp2 and sp3 C-H bond activation by platinum(II)

By merely changing the solvent, two different cyclometalated platinum complexes resulted from either sp(2) or sp(3) C-H bond activation can be prepared selectively. For example, the reaction of L1 with K(2)PtCl(4) in MeCN gave exclusively kinetic product 1a, while the reaction in AcOH was thermodyna...

description By merely changing the solvent, two different cyclometalated platinum complexes resulted from either sp(2) or sp(3) C-H bond activation can be prepared selectively. For example, the reaction of L1 with K(2)PtCl(4) in MeCN gave exclusively kinetic product 1a, while the reaction in AcOH was thermodynamically controlled and produced predominantly 1b.
