WebTransfer hydrogenation between alcohols and carbonyl compounds via C–H bond cleavage is well known, whereas transfer hydrocarbylation remains a challenge due to the cleavage of the unactivated C–C bond. Herein, we disclose a transfer methylenation approach towards various secondary and tertiary alcohols from abundant chemical feedstocks. WebAnalogously, transfer hydrocarbylation could greatly increase the versatility of tertiary alcohols. However, this reaction remains unexplored because of the challenges associated with the catalytic cleavage of unactivated C–C bonds. Herein, we report a rhodium(I)-catalyzed shuttle arylation cleaving the C ...
