Abstract
Disclosed is a process of forming a bis(azinyl)amine-BFcomplex, where a boron atom is complexed by two ring nitrogens of a deprotonated bis(azinyl)amine compound, comprising the step of reacting BFwith a protonated bis(azinyl)amine in the presence of a polar aprotic organic solvent that is not reactive with the BFunder reaction conditions. Such process provides good yields, even when a bulky group is present on the bis(azinyl)amine compound.
