Photochemical Cobalt-Catalyzed Hydroalkynylation to Form 1,3-Enynes
Grenier-Petel, Jean-Christophe,Collins, Shawn K.
, p. 3213 - 3218 (2019/04/13)
A photochemical hydroalkynylation is reported employing a metallaphotoredox approach using cobalt catalysis and an organic dye, 4CzIPN. The protocol enables catalysis without the need for stoichiometric metal reductants, normally needed to convert higher
Cobalt-Catalyzed Cross-Couplings of Bench-Stable Alkynylzinc Pivalates with (Hetero)Aryl and Alkenyl Halides
Hammann, Jeffrey M.,Thomas, Lucie,Chen, Yi-Hung,Haas, Diana,Knochel, Paul

A catalytic system consisting of CoCl2·2LiCl and TMEDA enables the cross-coupling of various electron-poor aryl and heteroaryl halides with various alkynylzinc pivalates. Coupling with alkenyl halides proceeds with retention of configuration.
Rhodium-catalyzed (E)-selective cross-dimerization of terminal alkynes

Cross-dimerization of various terminal alkynes with different bulky terminal alkynes such as triisopropylsilylacetylene and 1-trimethylsilyloxy-1,1- diphenyl-2-propyne efficiently proceeds in the presence of a rhodium catalyst system to produce the corresponding (E)-enynes with high regio- and stereoselectivity.

USEFUL SYNTHETIC REAGENTS DERIVED FROM 1-TRIISOPROPYLSILYLPROPYNE AND 1,3-BISPROPYNE. DIRECT, STEREOSELECTIVE SYNTHESIS OF EITHER Z OR E ENYNES
Corey, E. J.,Ruecker, Cristoph
, p. 719 - 722 (2007/10/02)
Lithio reagents derived from 1-triisopropylsilylpropyne (1) and 1,3-bis-propyne (3) are effective for the synthesis of Z or E terminal enyne units (CH=CH-CCH) and for carbon-carbon bond formation with halides, aldehydes, ketones, epoxides, and α,β-enones.
