Alkynylation of ferrocene by terminal alkynes. Part I. A simple one-step synthesis of ferrocenylacetylenes
Dyadchenko, Victor P.,Dyadchenko, Marina A.,Okulov, Vladimir N.,Lemenovskii, Dmitri A.
, p. 468 - 472 (2011)
Ferrocene reacts with terminal alkynes in the presence of copper and iron salts to give 1-ferrocenyl-2-R-alkynes (R - substituent). This direct cross-coupling of ferrocenyl and alkynyl moieties allows for the preparation of ferrocenyl substituted alkynes

supporting information, p. 6764 - 6769 (2017/07/15)
A palladium-catalyzed Sonogashira-type coupling between arylsulfonyl hydrazides and terminal alkynes via Ar(C)-S bond cleavage is disclosed, which enables the general synthesis of functionalized internal alkynes, especially the Br-substituted ones, in good to excellent yields under acid- and base-free conditions.

Pawluc, Piotr,Hreczycho, Grzegorz,Madalska, Martyna,Szudkowska, Justyna,Kubicki, Maciej,Marciniec, Bogdan
experimental part, p. 3843 - 3847 (2010/03/03)
A series of new 2-aryl-1,1-bis(trimethylsilyl)ethenes containing ortho-, meta-, and para-substituted aryl or heteroaryl groups has been efficiently synthesized using an improved two-step approach based on a silylative coupling cyclization-Heck coupling/Gr
