Cobalt-catalyzed cross-coupling of alkynyl Grignard reagents with alkenyl triflates

Alkenyl triflates in combination with Co(acac)3 as a catalyst were found to be excellent coupling partners of alkynyl Grignard reagents, where no special additives (even a phosphine ligand) but a common solvent, THF, are required to obtain vari

Triple-Bond Insertion Triggers Highly Regioselective 1,4-Aminomethylamination of 1,3-Enynes with Aminals Enabled by Pd-Catalyzed C-N Bond Activation

A highly chemo- and regioselective 1,4-aminomethylamination of simple enynes with aminals to allenic 1,5-diamines by taking advantage of C-N bond activation has been reported. The reaction proceeds under mild reaction conditions and can be performed under

Insertion of 1-chloro-1-lithioalkenes into organozirconocenes. A versatile synthesis of stereodefined unsaturated systems

Hydrozirconation of alkenes and alkynes, followed by insertion of 1- halo-1-lithio-1-alkenes, generated in situ by lithium tetramethylpiperidide deprotonation of vinyl halides, affords vinylzirconocene species which may be further elaborated. The method provides easy access to many structures including terminal (3E)- and (3Z)-1,3-dienes and (3E,5E)- and (3Z,5E)-1,3,5- trienes, and internal (E,Z)-dienes,(E,Z,E)-trienes, and (1E, 3Z)1,3-dien-5- ynes. Insertion of 2-monosubstituted 1-halo-1-lithio-1-alkenes occurs with clean inversion of configuration of the sp2-carbenoid carbon. Carbenoids derived by deprotonation of 2,2-disubstituted 1-halo-1-alkenes gave poor stereocontrol probably due to isomerization before insertion into the organozirconium species. Insertion of vinyl carbenoids into alkynylzirconocenes affords terminal (3E)- or (3Z)-1,3-dien-5-ynes, internal (1E,3Z)-1,3-dien-5-ynes, and (Z)-3-en-1,5-diynes.
