A general synthetic approach to molecular structures that are hybrids of tetraethynylethylene (TEE) and tetravinylethylene (TVE) is reported. The synthesis permits the controlled preparation of many previously inaccessible structures, including examples w
Radical Reactions of 1,4-Alkadiynes: Metal Coordination as an Effective Tool for Controlling the Regio- and Stereoselectivity of the C-C Bond Formation
Melikyan, Gagik G.,Anker, Bryan
supporting information, p. 4194 - 4197 (2015/09/22)
A novel method for selective generation of radicals in 1,4-alkadiynes is developed by employing a π-bonded Co2(CO)6 core as a triple-bond immobilizing, cation-stabilizing, and radical-guiding auxiliary group. The isolation of α-alkyn
A simple synthesis of tetraethynylethenes and representative molecular structures of some dicobalt derivatives

Palladium-copper catalysed cross-coupling reactions of tetracholoroethene with terminal acetylenes RC≡CH (R = SiMe3, C6H5, C6H4CN-4) in refluxing triethylamine afford the corresponding tetraethynylethenes in 30-60% isolated yields. The reaction of 1,6- bis(trimethylsilyl)-3,4-bis (trimethylsilylethynyl)-hex-3-ene-1,5-diyne with [Co2(CO)6(L2)] [L2 = (CO)2 or μ-dppm] affords complexes in which one or two (trans) acetylene moieties are coordinated by a dicobalt fragment.

Tetraphenyltetraethynylethene and the ?-acceptors 2,4,7-trinitrofluoren-9-one and (2,4,7-trinitro-9-fluorenylidene)malononitrile form highly ordered donor-acceptor ?-complexes having 1:2 stoichiometry in the solid state; in solution, relatively weak 1:1 c
New Planar ?-Systems, II. - On the Preparation and Structure of Tetrakis(phenylethynyl)ethene
Hopf, Henning,Kreutzer, Martin,Jones, Peter G.
, p. 1471 - 1475 (2007/10/02)
The preparation of tetrakis(phenylethynyl)ethene (1b) has been repeated.Among various routes to this highly unsaturated cross-conjugated ?-system, the dimerization of bromide 2 via the carbene 3 is the most simple one.Full spectroscopic data for 1b are re
