The gem-selective cross-dimerization and -trimerization of silylacetylenes with alkynes through C-H activation using a rhodium(I)-pyridine-N-heterocyclic carbene catalyst have been developed. This reaction is applied to various aliphatic or aromatic termi

A CoCl2·6H2O/Zn reagent using 2-(2,6-diisopropylphenyl)iminomethylpyridine (dipimp), 1,2- bis(diphenylphosphino)ethane (dppe), or 1,2-bis(diphenylphosphino)benzene (dppPh) as a ligand effectively catalyzed the cross-addition reaction

The cross-dimerization of diphenylacetylene with trimethylsilylacetylene via C-H bond cleavage in the presence of a catalytic amount of bis(cyclooctadiene)nickel [Ni(cod)2] together with a pyridine-based ligand efficiently proceeds to give the corresponding enyne compound with good yield. In contrast, their 1:2 cross-trimerization leading to a dienyne derivative takes place selectively using a triarylphosphine ligand. The regioselective cross-dimerization of some unsymmetrical internal arylalkynes with terminal silylacetylenes is also accomplished using the pyridine ligand.
Rhodium-catalyzed anti selective cross-addition of bis(trimethylsilyl)- acetylene to diarylacetylenes via carbon-silicon bond cleavage
Horita, Akinobu,Tsurugi, Hayato,Satoh, Tetsuya,Miura, Masahiro
scheme or table, p. 1751 - 1754 (2009/04/12)
The addition of bis(trimethylsilyl)acetylene to diarylacetylenes proceeds efficiently and selectively in a formal anti fashion in the presence of [Rh(OH)(cod)]2/bisphosphine and phenol as catalyst and activator, respectively, accompanied by cleavage of one of the C-Si bonds to produce the corresponding (Z)-enynes. The products can further couple with the same or a different diarylacetylene molecule to give rise to (Z,Z)-1,2,5,6-tetraaryl-1,5- hexadien-3-ynes that show relatively strong solid-state fluorescence.
Palladium-catalysed cross-coupling reactions of triorganoindium reagents with alkenyl halides
Riveiros, Ricardo,Saya, Lucia,Sestelo, Jose Perez,Sarandeses, Luis A.
experimental part, p. 1959 - 1966 (2009/04/03)
The regio- and stereoselectivity of the palladium-catalysed cross-coupling reactions of indium organometallics with stereodefined 1-haloalkenes and 1,1-dihaloalkenes have been studied. Triorganoindium reagents (R3In; R = alkyl, alkenyl, aryl an
