Abstract: The exceptionally π-basic metal fragments {MoTp-(NO)(DMAP)} and {WTp(NO)(PMe3)} (Tp = tris(pyrazolyl)borate; DMAP = 4-(N,N-dimethylamino)pyridine) form thermally stable η 2-coordinated complexes with a variety of electron-deficient arenes. The tolerance of substituted arenes with fluorine-containing electron withdrawing… read more here.

DOI: 10.1021/acs.orglett.8b03871
Abstract: One formidable challenge in sp2 C-H activation is how to achieve high para selectivity on electron-deficient arenes because such site selectivity is disfavored by the electronic bias induced by the electron-withdrawing groups. The first highly… read more here.
