Herein we report a transition metal free catalytic terminal alkyne functionalization across the C-X triple bond (X = CH and N) with E-selective homo (alkyne-alkyne) and head-to-tail selective hetero (alkyne-nitrile) dimerization. A series of stoichiometric reactions enabled us to crystallize a reactive organometallic intermediate K-arylacetylide complex which was characterized by X-ray crystallography, indicating that an ionic mechanism is operative.

Palladium-Catalyzed C-H Alkynylation of Unactivated Alkenes.

The systematic study reveals that substrates are tolerated with a wide range of substituents on the olefin and bromoalkyne coupling partners, and chemicaloselective transformations were demonstrated for amides, olefins, and alkynes obtained.

Dimerization of terminal alkynes promoted by a heterobimetallic Zr/Co complex.

This work demonstrates the formation of 1,3-enynes from terminal alkynes facilitated by a reduced ZrIV/Co-I heterobimetallic complex, revealing that bimetallic activation of the terminal C-H bond of the alkyne is an essential mechanistic step.

DFT study on the [4+4] domino cycloaddition of ynones with benzylidenepyrazolones to access eight-membered cyclic ethers: effects of DBUvs.Et3N

The difference in the catalytic activity of bases is primarily attributed to their electron-donating ability (t-BuO−> DBU > Et3N).

Rhodium(I)-NHC Complexes Bearing Bidentate Bis-Heteroatomic Acidato Ligands as gem-Selective Catalysts for Alkyne Dimerization.

Investigation of the reaction mechanism supports a non-oxidative pathway in which the BHetA ligand behaves as proton shuttle through intermediate κ 1 -HBHentA species, however, in the presence of pyridine as additive, the identification of the common Rh III H(C≡CPh) 2 (IPr)(py) 2 intermediate gives support for an oxidative route.



Cyclic (Alkyl)amino Carbene Based Iron Catalyst for Regioselective Dimerization of Terminal Arylalkynes

[(cAAC)Fe(CO)4] (1) catalyzed head-to-head dimerization of terminal arylalkynes toward conjugated enynes in very high yield and high E selectivity (up to 84:16 E:Z). The protocol can be performed

Iron catalyzed highly regioselective dimerization of terminal aryl alkynes.

Iron can catalyze head-to-head dimerization of terminal aryl alkynes to give the corresponding (E) selective conjugated enynes in high yields. A variety of substituted aryl acetylenes underwent

Z-Selective (Cross-)Dimerization of Terminal Alkynes Catalyzed by an Iron Complex.

The complex [Fe(H)(BH4 )(iPr-PNP)] catalyzed the (cross-)dimerization of alkynes at room temperature, with no need for a base or other additives, to give the corresponding dimerized products with Z selectivity in excellent yields.

C-C Bond Formation of Benzyl Alcohols and Alkynes Using a Catalytic Amount of KOt Bu: Unusual Regioselectivity through a Radical Mechanism.

We report a C-C bond-forming reaction between benzyl alcohols and alkynes in the presence of a catalytic amount of KOt Bu to form α-alkylated ketones in which the C=O group is located on the side

Functionalization of Alkynes Catalyzed by t-Bu-P4 Base

The addition of O- and N-nucleophiles to alkynes catalyzed by a phosphazene base, t-Bu-P4 base, was investigated. Alkynes were easily transformed to enol ethers and enamines in DMSO by the addition

Active Iron(II) Catalysts toward gem-Specific Dimerization of Terminal Alkynes

The syntheses and catalytic activity of a series of piano-stool iron complexes with the general formula [FeClCp*(NHC] toward the gem-specific dimerization of terminal alkynes are reported, which is more active and features the same geminal specificity.
