Abstract
A simple and efficient Rh2(OAc)4/DPPM (bis(diphenylphosphanyl)methane) catalyzed regioselective 1,2-anti-Markovnikov hydrosilylation of conjugated dienes with various tertiary silanes gave homoallylic silanes in acetonitrile, which tolerate broad functional groups. Control experiments proved that no π-allyl transition metal intermediates were involved in this 1,2-anti-Markovnikov hydrosilylation. Dirhodium hydride species was observed in hydrosilylation, suggesting that a direct insertion of the terminal double bond into a Rh-H bond is involved in this reaction.

Abstract
An oxidative cascade [4 + 2] radical cycloaddition/dehydroaromatization reaction of aryl alkenes to access α-aryl substituted naphthalenes under redox-neutral conditions was achieved. This reaction was found to require the addition of [Cu] catalyst along with stoichiometric concentrations of NFSI as a trigger of radical series of steps. Norbornene (NBE), rather than the conventional oxidant, manifested optimal performances as a H-acceptor in this procedure. The results herein might shed encouraging insight into the transition-metal-catalyzed dehydrogenative C-H activation protocols.
