Copper-catalyzed Z-selective semihydrogenation of alkynes with hydrosilane: A convenient approach to cis-alkenes

A copper catalyst generated in situ from widely available copper salt and imidazolium salt in the presence of t-BuOK showed high efficiency for the semihydrogenation of a wide range of internal and terminal alkynes to their corresponding alkenes without obvious over-reduction. Functional groups, such as hydroxyl, nitro, halides, and amino, etc. were tolerated. The Z/E ratios of the obtained alkenes were generally >99%. Finally, semireduction of bulky alkynes also went smoothly.

Stereospecific Synthesis of 1,4-Dienes by Cross-Coupling of Allyl Halides with Alkenylcopper Intermediates from Alkenyldialkylboranes

Alkenylcopper intermediates, generated from alkenyldialkylborane derivatives of 9-borabicyclononane (9-BBN) and dicyclohexylborane (DCB), undergo stereospecific cross-coupling with allylic halides to yield stereodefined 1,4-dienes.
