Atom economy and esters: compatible now! The first catalytic insertion of a CC bond into an acyl CO bond was achieved using rhodium catalysts (see scheme). The products are β‐alkoxy ketones with a fully substituted carbon center. Quinoline chelating groups were employed to stabilize the Rh‐alkoxide intermediate.

In this context, reactions mediated by silyl radicals have become increasingly attractive but methods for accessing these intermediates remain limited. We present a new strategy for silyl radical generation via electroreduction of readily available chlorosilanes. At highly biased potentials, electrochemistry grants access to silyl radicals through energetically uphill reductive cleavage of strong
