palladium‐catalyzed carbene insertion into C(sp3)−H bonds leading to pyrrolidines was developed. The coupling reaction can be catalyzed by both Pd0 and PdII, is regioselective, and shows a broad functional group tolerance. This reaction is the first example of palladium‐catalyzed C(sp3)−C(sp3) bond assembly starting from diazocarbonyl compounds. DFT calculations revealed that this direct C(sp3)−H bond functionalization

Highly efficient Ru-catalyzed selective C-C or C-O bond cleavage of polyols (e.g., crude glycerol) for N-hydroxyethylation or N-acetonylation of amines was achieved through the hydrogen-borrowing approach. A variety of amines were transformed to the desired amino alcohols/ketones in moderate-to-excellent yields, opening up new avenues for generation of oxygenated pharmaceuticals and fine chemicals
The present teachings relate to organic semiconductor formulations including an organic semiconducting compound in a liquid medium, where the liquid medium includes (1) a compound in liquid state that has electronic properties complementary to the electronic structure of the organic semiconducting compound and optionally (2) a solvent or solvent mixture for solubilizing the organic semiconducting compound. The present formulations can be used as inks in the fabrication of organic semiconductor devices.
