Electrochemical Hydrosilylation of Alkynes
ACS Organic & Inorganic Au, 2022 Herein, the electrochemical hydrosilylation of alkynes is reported. In the presence of the Suginome reagent (PhMe2Si-Bpin), a large panel of terminal alkynes and internal alkynes was successfully converted into the hydrosilylated product in good to excellent yields and good selectivity in favor of the linear product.

Decarboxylative Hydroalkylation of Alkynes [PDF]
Journal of the American Chemical Society, 2018 The merger of open- and closed-shell elementary organometallic steps has enabled the selective intermolecular addition of nucleophilic radicals to unactivated alkynes. A range of carboxylic acids can be subjected to a CO2 extrusion, nickel capture, migratory insertion sequence with terminal and internal alkynes to generate stereodefined functionalized ...

Masked alkynes for synthesis of threaded carbon chains [PDF]
, 2023 Polyynes are chains of sp1 carbon atoms with alternating single and triple bonds. As they become longer, they evolve towards carbyne, the 1D allotrope of carbon, and they become increasingly unstable.
