We have developed a practical and mild electrochemical protocol for cyanation and cyanomethylation of trimethylammonium salts through a pathway involving C–N bond cleavage without the need for an exter-nal stoichiometric reducing agent or a sacrificial anode.The reaction employs tosyl cyanide(TsCN)or azido allyl alcohol as the cyanation or cyanomethylation reagent,respectively.It shows high functional group compatibility and can be applied for the cyanation of natural product derivatives.Preliminary mechanistic studies indicate the involvement of a radical addition pathway. 展开更多

Highly enantioselective and diastereoselective 1,2-diarylation and 1,2-arylalkynylation of trisubstituted alkenes are reported via the palladium-catalyzed Heck/Suzuki or Heck/Sonogashira domino sequence.These alkenes represent an extension of enantioselective dicarbofunctionalization from terminal alkenes to trisubstituted ones based on anionic capture of the secondary alkyl-Pd intermediate. 展开更多
