Palladium-catalyzed alkene-directed cross-coupling of aryliodide with another aryl halide through C-H arylation opens a unique avenue for unsymmetrical biaryl-derived molecules. However, homo-coupling of aryliodides often erodes the overall synthetic efficiency. Reported herein is a highly chemoselective Pd0 -catalyzed alkyne-directed cross-coupling of aryliodides with bromophenols, which was subsequently

A palladium(0)-catalyzed dearomatizing [3+2] spiroannulation of naphthalene-based biaryls with arynes has been developed for the rapid construction of spirofluorene architectures. This reaction was realized by carbopalladation of aryne to generate an arylpalladium species, followed by termination with naphthalene dearomatization, which is a sharp contrast to the conventional C–H functionalization approach
