Ano, Yusuke published the artcilePalladium-catalyzed 1,1-alkynylbromination of alkenes with alkynyl bromides, Product Details of C10H10O2, the main research area is propargylic bromide preparation regioselective; alkynyl bromide terminal alkene alkynylbromination palladium catalyst.
The palladium-catalyzed 1,1-alkynylbromination of terminal alkenes RC=CH2 (R = Ph, naphthalen-2-yl, 1-benzofuran-2-yl, etc.) with a (bromoethynyl)triisopropylsilane is reported. The method tolerates a diverse range of alkenes to afford propargylic bromides RCH2CH(Br)CCSi(CH(CH3)2)3 regioselectively. Mechanistic studies and DFT calculations indicate that the 1,1-alkynylbromination reaction proceeds via the migration of the Pd center followed by the formation of a π-allenyl Pd intermediate, leading to the stereoselective reductive elimination of the C(sp3)-Br bond at the propargylic position.
