A palladium-catalyzed oxidative ortho-acylation of 2-arylbenzoxazoles and 2-arylbenzothiazoles using TBHP as oxidant was developed, in which readily available toluene derivatives were used as the in situ generated acyl sources. This reaction afforded the desired products in moderate to good yields, and exhibited excellent regioselectivity. The plausible mechanism was also proposed.

A facile and efficient way for the synthesis of the acylated 2-arylbenzoxazoles and 2-arylbenzothiazoles by heterocycle-directed ortho-acylation was developed. This reaction was performed in chlorobenzene, using arylmethyl alcohols and tert-butyl hydroperoxide (TBHP) as the easily accessible acyl source and the oxidant, respectively, affording the desired products in moderate to good yields.
