A mild method for adding silyl groups to unactivated aromatic rings has been discovered by chemists at the University of California, Berkeley. The reaction could provide a valuable route to arylsilane monomers for making silicone polymers. And because silyl groups can undergo a number of transformations to different functional groups, the reaction could be used to make arylsilane intermediates en route to more complex molecules.

Current methods to add silyl groups require temperatures above 100 . . .
