A simple and effective Pd(ii)-catalyzed regioselective C(2)-H arylation of 6,5-fused heterocycles with dioxazolones as a masked ester surrogate under mild conditions is reported. The significance of the arylation is highlighted by the new reactivity demonstrated in dioxazolones via proximal C-H activation of the cyclic carbonate of the hydroxamic acid functionality under protic conditions.

A improved method for the preparation of 2,3-unsubstituted benzofurans is described.Specifically, the PPA catalysed cyclization of aryloxyacetaldehyde acetals to give (4-7)-substituted benzofurans has been achieved.
