Rollover-assisted C(sp2)-C(sp3) bond formation

Rollover cyclometalation involves bidentate heterocyclic donors, unusually acting as cyclometalated ligands. The resulting products, possessing a free donor atom, react differently from the classical cyclometalated complexes. Taking advantage of a rollover / retro-rollover reaction sequence, a succession of oxidative addition and reductive elimination in a series of platinum(II) complexes [Pt(N,C)(Me)(PR3)] resulted in a rare C(sp2)-C(sp3) bond formation to give the bidentate nitrogen ligands 3-methyl-2,2′-bipyridine, 3,6-dimethyl-2,2′- bipyridine, and 3-methyl-2-(2′-pyridyl)-quinoline, which were isolated and characterized. The nature of the phosphane PR3 is essential to the outcome of the reaction. This route constitutes a new method for the activation and functionalization of C-H bond in the C(3) position of bidentate heterocyclic compounds, a position usually difficult to functionalize. Rock and rollover! Rare cases of C(sp2)-C(sp3) bond formation from Pt IV cyclometalated complexes are described, through a succession of oxidative addition and reductive elimination reactions, taking advantage of a rollover / retro-rollover sequence (see scheme).
