An efficient, selective and scalable C–H amidation of s-tetrazines under iridium(III) catalysis is reported. This reaction features a broad substrate scope, high functional group tolerance, and air and water tolerance. This reaction also shows great potential for the rapid preparation of tri- and tetra-functional building blocks, which can be applied either in bioconjugation or synthesis of DNA-encoded library.

We report a general palladium-catalyzed one-pot procedure for the synthesis of phosphonates, phosphinates and phosphine oxides from phenols mediated by sulfuryl fluoride. It features mild conditions, broad substrate scope, high functionality tolerance and water insensitivity. The utility of this procedure has been well demonstrated by gram-scale synthesis, sequential synthesis of click chemistry building blocks, late-stage decoration of drugs and natural products and on-DNA synthesis of phosphine oxide for a DNA-encoded library (DEL).
