Angewandte Chemie, EarlyView.The synthesis and catalytic properties of Ni(II) complexes, with the general formula Ni(NHC)[P(OR)3](Ar)Cl, are described. These air‐stable complexes are effective under mild conditions and low catalytic loading for the Suzuki‐Miyaura cross‐coupling for a range of electronically and sterically differentiated coupling partners.

5-(Benzoyloxymethyl)isoxazole-3-carboxylic Acid Ethyl Ester
MolbankWe describe here the palladium hydrogenation of ethyl 5-(benzoyloxymethyl)isoxazole-3-carboxylate. The presence of two reducible sites in the molecule, namely the benzylic-like position and the isoxazole N–O bond, creates a possible competition.

Ring-Opening Fluorination of Isoxazoles
Organic Letters, 2022 A ring-opening fluorination of isoxazoles has been developed. By treating isoxazoles with an electrophilic fluorinating agent (Selectfluor®), fluorination followed by deprotonation leads to tertiary fluorinated carbonyl compounds. The present method features mild reaction conditions, good functional group tolerance, and simple experimental procedure ...
