A transition‐metal‐free (5+1) cycloaddition of aryl‐substituted vinylcyclopropanes (VCPs) and hydrosilanes to afford silacyclohexanes is reported. Catalytic amounts of the trityl cation initiate the reaction by hydride abstraction from the hydrosilane, and further progress of the reaction is maintained by self‐regeneration of the silylium ions. The new reaction involves a [1,2] migration of an aryl

Herein, we report the successful implementation of reductive strategy in the ring opening reaction of aryl cyclopropyl ketones with unactivated alkyl bromides. Under the catalysis of nickel, this reductive Csp3–Csp3 cross-coupling reaction proceeds with complete regioselectivity and bypasses the use of pregenerated organometallics, enabling efficient synthesis of alkylated ketones with high step economy
