A quinoline-oxazoline compound having the formula:
where one of X
1
and X
2
is N and the other is C and one of R1, R2 and R3 is Z wherein Z is an oxazoline radical having the formula
such that when X
1
is N R2 is Z and R1 is absent, and when X
2
is N either R1 or R3 is Z and R2 is absent. 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.

A selective oxidation of benzylic C(sp3)–H bonds to C(sp3)–O bonds catalyzed by copper complexes of quinoline–imine ligands was developed with peresters as oxidants under mild reaction conditions, which converted benzylic methylenes directly into benzylic alcohols and esters by means of direct C–H bond functionalization.

Palladium-Catalyzed Coupling of Oxazol-2-yl- and 2-Oxazolin-2-yltrimethylstannanes with Aromatic Halides. A New Entry to 2-Aryl and 2-Heteroaryl Oxazoles and Oxazolines
4-Methyloxazole and 4,4-dimethyl-2-oxazoline were treated with n-butyllithium and trimethyltin chloride to give the corresponding 2-trimethylstannyl derivatives which in the presence of tetrakis(triphenylphosphine)palladium(0) as a catalyst undergo cross-coupling reactions with various aryl and heteroaryl halides to give 2-aryl and 2-heteroaryl oxazoles and oxazolines in high yields.
