C–h functionalizationof heteroarenes usingunactivated alkyl halides through visible-light photoredox catalysisunder basic conditions... We reporta mild method under basic conditions that allows access to previouslyunderexplored regioselectivities by relying on a combination of conjugateand halogen ortho-directing effects....

Distinctive meta-directing group effect for iridium-catalyzed 1,1-diarylalkene enantioselective hydrogenation... We propose that a meta-directing group, 3,5-dimethoxyphenyl, is responsible for the observed enantioselection, the highest reported, to date, for iridium-catalyzed hydrogenation of 1,1-diarylalkenes lacking ortho-directing groups

Peracetic acid: an atom-economical reagent for pd-catalyzedacetoxylation of c–h bondsPeracetic acid canbe used universally as a source of acetate andan oxidant for the selective acetoxylation of C–H bonds incompounds containing ortho-directing groups, catalyzedby Pd(OAc)2....

Regioselective hydrostannation of highly hindered arylalkynes under ortho directing effects... The regioselectivity was found to be under the control of the ortho-substituents (ortho-directing effects, ODE) and pure α-vinylstannanes are produced in good yields and as single isomers regardless of the substituents’ nature....
