Stereoretentive radical cross-coupling. [PDF]
NatureFree radicals were first discovered over 120 years ago by Gomberg and the first radical cross-couplings demonstrated by Kochi in the 1970's. Fueled by the need for general methods to couple C(sp3)-fragments, this area has seen an explosion of renewed interest.

Cross-Coupling of Heteroatomic Electrophiles [PDF]
Chemical Reviews, 2019 At the advent of cross-coupling chemistry, carbon electrophiles based on halides or pseudohalides were the only suitable electrophilic coupling partners. Almost two decades passed before the first cross-coupling reaction of heteroatom-based electrophiles was reported.

Denitrative Cross-Couplings of Nitrostyrenes [PDF]
Molecules, 2020 Interestingly, β-nitrostyrenes, typically bench stable compounds, are highly promising cross-coupling partners, due to their excellent availability and well understood reactivity. In this review, we report on the discovery and advancements, in the field of stereoselective, denitrative cross-couplings of β-nitrostyrenes with miscellaneous organic ...

Cross-coupling Reactions of Monosubstituted Tetrazines [PDF]
Organic Letters, 2021 A fast and mild method for the Pd-catalyzed cross-coupling reaction of monosubstituted 3-bromo-1,2,4,5-tetrazine is presented. Investigation of silver-based additives revealed that Ag2CO3 is the optimal mediator, enabling the process without the need for strong bases or high temperatures.
