CLAIMS:
1. A process of forming a bis(azinyl)amine-BF2 complex, where a boron atom is complexed by two ring nitrogens of a deprotonated
bis(azinyl)amine compound represented by Formula (1):


wherein:
A and A' represent independent azine ring systems corresponding to 6-membered aromatic ring systems containing at least one nitrogen;
each Xa and Xb is an independently selected substituent, two of which may join to form a fused ring to A or A';
m and n are independently 0 to 4; and
atoms 1, 2, 3, 4, 1', 2', 3', and 4' are independently selected as either carbon or nitrogen atoms. ,

comprising the step of reacting BF3 with a protonated bis(azinyl) amine in the presence of a polar aprotic organic solvent represented by formula 3:


wherein
Ri, R2 and R3 each independently represents hydrogen, fluorine, alkyl, aryl, alkoxy, aryloxy, dialkylamino, diarylamino, cyano, or nitro groups; and Ri and R2, R2 and R3 or Ri and R3 may join to form a cycloalyl or an aryl ring group.that is not reactive with the BF3 under reaction conditions.

2. The process of claim 1 wherein the polar aprotic organic solvent contains a nitrile group.

3. The process of claim 2 wherein Ri in formula 3:
represents a perfluoroalkyl group..

4. The process of claim 3 wherein at least one of Ri, R2 and R3 is not H.

5. The process of claim 3 wherein at least two of Rj., R2 and R3 are not H.

6. The process of claim 3 wherein Ri and R2 represent H and R3 represents a methyl group.

7. The process of claim 3 wherein Ri and R2 represent H and R3 represents an ethyl group.

8. The process of claim 3 wherein at least two of Rls R2 and R3 are H.

9. The process of claim 1 wherein the BF3 source comprises BF3 gas, BF3 solution in an organic solvent or BF3 complex with organic solvent or compound.

10. The process of claim 1 wherein the BF3 source comprises BF3 complexed with diethyl ether, dimethyl ether or tetrahydrofuran.

11. The process of claim 1 wherein BF3 is used in the amount 1 -50 equivalents per mol of protonated bis(azinyl)amine compound.

12. The process of claim 1 wherein the reaction is performed at a temperature of at least 18°C.

13. The process of claim 1 wherein the reaction is performed at a temperature of at least 80°C.

14. The process of claim 1 wherein the reaction is performed at a temperature of at least 115°C.

15. The process of claim 1 where at least one X or Xb is present containing 4 or more carbon atoms.

16. The process of claim 15 wherein the Xa or Xb group is selected from the group consisting of phenyl and t-butyl groups.

17. The process of claim 15 wherein the X a o „_r v Xb group is a phenyl group.

18. The process of claim 16 wherein the Xa or Xb group is a phenyl group containing at least one methyl group substituent.

19. The process of claim 16 wherein the X aa o „-r X vb group is a mesityl group.

20. The process of claim 1 wherein the a bis(azinyl)amine-BF2 complex is selected from the following:
