A tandem one-pot Friedel-Crafts alkylation/double cyclization process to conveniently assemble diaryl-fused 2,8-dioxabicyclo[3.3.1]nonanes with aryl substituents at the C-1 position was developed. 2-Hydroxychalcones and naphthol derivatives reacted in refluxing toluene with ( D, L)-10-camphorsulfonic acid (CSA) as the catalyst. The transformation conveniently provided the corresponding 2,8-dioxabicyclo[3.3.1]nonanes fused with one phenyl and one naphthyl group in moderate to good yields, and various substitutions on both reaction partners were tolerated. More importantly, aryl- and aza-aryl-fused 2,8-dioxabicyclo[3.3.1]nonanes were prepared for the first time using this procedure. [ABSTRACT FROM AUTHOR]

A number of N-heterocycles have been tested as directing group in the novel Ru-catalyzed regioselective ortho-selenylation of benzene featuring 2-pyridinyl and 1-pyrazolyl groups as most promising candidates that have been further examined in a broad variety of arenes. [ABSTRACT FROM AUTHOR]
