Rhodium(I)-catalyzed addition of arylboronic acids to β-(arylethynyl) ketones proceeds through 1,4-rhodium migration to afford 4-(arylmethylene)tetralin-1-ols, which upon treatment with triflic anhydride furnish (arylmethyl)naphthalenes through sequential dehydration–aromatization. Fused aromatic compounds with three to five rings have been prepared using the arylative annulation strategy.

Herein, the first example of gold-catalyzed benzylation of (hetero)aryl boronic acids with (hetero)benzyl bromides to give the corresponding cross-coupling products in moderate to good yields is reported. The reaction proceeds through a possible intermolecular SN2-type reaction pathway to give a wide variety of di(hetero)arylmethanes as the desired products. An intriguing reaction mechanism has been proposed on the basis of control experiments, 31P-NMR spectroscopic detection and DFT calculations.

A highly efficient Bi(OTf)3-catalyzed benzylation of arenes and heteroarenes has been developed. The mild reaction conditions, high yields, operational simplicity and practicability, broad scope, and remarkably low catalyst loading render this environment friendly process an attractive approach to diarylmethane derivatives. The extension to an intramolecular variant of this procedure provides a valuable route to substituted fluorenes.
