Copper Catalyzed Decarboxylative Alkynylation of Quaternary α-Cyano Acetate Salts
摘要:
Cu-catalyzed decarboxylative alkynylation of quaternary a-cyano acetate salts with alkynyl bromides and alkynyl chlorides is described. This new reaction can be used for preparing functionalized butynenitrile derivatives.

for C(sp3)-C(sp) cross-coupling with terminalalkynes has been developed by using a multi-metal-catalyzed reaction strategy. Alkyl radicals generated from different approaches are able to couple with terminalalkynes by judicious selection of the catalyst combination. This reaction protocol offers an efficient alternative approach for the synthesis of substituted alkynes from terminalalkynes besides
