ABSTRACT:
Disclosed is a process of forming a bis(azinyl)amine-BF2complex, where a boron atom is complexed by two ring nitrogens of a deprotonated bis(azinyl)amine compound, comprising the step of reacting BF3with a protonated bis(azinyl)amine in the presence of a polar aprotic organic solvent that is not reactive with the BF3under reaction conditions. Such process provides good yields, even when a bulky group is present on the bis(azinyl)amine compound.
