A Transient Directing Group Strategy Enables Enantioselective Multicomponent Organofluorine Synthesis. [PDF]
The vicinal fluorofunctionalization of alkenes represents an expedient strategy for converting feedstock olefins into valuable fluorinated molecules and as such has garnered significant attention from the synthetic community; however, current methods ...

Copper-mediated oxidative C−H/N−H activations with alkynes by removable hydrazides
The efficient copper-mediated oxidative C–H alkynylation of benzhydrazides was accomplished with terminal alkynes. Thus, a heteroaromatic removable N-2-pyridylhydrazide allowed for domino C–H/N–H functionalization.

Catalyst design in C-H activation: a case study in the use of binding free energies to rationalise intramolecular directing group selectivity in iridium catalysis. [PDF]
Remote directing groups in a bifunctional molecule do not always behave independently of one another in C–H activation chemistries. A combined DFT and experimental mechanistic study to provide enhanced Ir catalysts for chemoselective C–H deuteration of ...

Transient Directing Group enabled C3-(sp2)-H alkenylation of Five Membered Heterocyclic Aldehydes: An Easy Access to Mechanochromic Luminogens [PDF]
The palladium (II) catalyzed direct C3-(sp2)-H alkenylation of five membered heterocyclic aldehydes has been developed using 3-aminobutanoic acid as a catalytic transient directing group.

Grouping with Directed Relationships [PDF]
Grouping is a global partitioning process that integrates local cues distributed over the entire image. We identify four types of pairwise relationships, attraction and repulsion, each of which can be symmetric or asymmetric. We represent these relationships with two directed graphs.

Imine as a linchpin approach for meta-C–H functionalization
Site-selective C–H functionalization still faces some challenges, such as the introduction and removal of an appropriate directing group. Here, the authors introduce a temporary directing group for selective meta-C–H functionalization of 2 ...
