anhydrous Suzuki–Miyaura cross-coupling of alkylboronic esters with aryl halides is described. Parallel experimentation revealed that the combination of AntPhos, an oxaphosphole ligand, neopentyldiol alkylboronic esters, and potassium trimethylsilanolate (TMSOK) enables successful cross-coupling. In general, reactions proceed in under 1 h with good yields and high linear/branched (l/b) selectivities. Crucially

Electrochemically generated organonickel sigma-complexes were used as model compounds to study the kinetics of oxidative addition of ArNi(I)bpy to RX, the key stage of cross-coupling of organic halides (RX). The reaction rate constants were calculated, and the sequence of relative reactivity of RX toward the electrochemically generated MesNi(I)bpy complex was obtained.
