Each of these compounds may be prepared in situ in a reactor. The instant process controls the pressure in the reactor through continuous venting of by-product HCl at elevated pressures. The instant invention also utilizes an excess of of reactive solvent such as PCl 3 , XPCl 2 , or X 2 PCl as X is defined above.

R1 and R3 through R12 are independently H or a pendant moiety which does not interfere with coordination of either N in the quinoline compound with a coordination center. These compounds can be complexed with a suitable coordination center such as catalytically active palladium and can be highly useful in catalytically oxidizing alkenes with high regioselectivity.
