Transition-metal-free synthesis of conjugated polymers from bis-grignard reagents by using TEMPO as Oxidant

(Figure Presented) Increasing the TEMPO! Transition metals are not necessary for oxidative polymerization of 2,7-di-magnesated fluorenes. Oxidation readily occurs by using the commercially available 2,2,6,6-tetramethyl-piperine 1 -oxyl radical (TEMPO) as

Ferrocene metallopolymers of intrinsic microporosity (MPIMs)

We show here that non-network metallopolymers can possess intrinsic microporosity stemming from contortion introduced by metallocene building blocks. Metallopolymers constructed from ferrocenyl building blocks linked by phenyldiacetylene bridges are synth

Glaser coupling at metal surfaces

On-surface synthesis is a promising approach for constructing covalently bound nanostructures. However, the number of reliable chemical reactions suitable for on-surface chemistry is very limited. Arylalkynes can be coupled at various surfaces in a novel

Macrocyclic cyclophanes with two and three α,ω-dichalcogena-1, 4-diethynylaryl units: Syntheses and structural properties

(Chemical Equation Presented) By means of four- and six-component cyclization reaction various cyclophanes were synthesized. The components were the di(lithium) salts of 1,4-di(ethynyl)benzene (11), 4,4′-di(ethynyl) biphenyl (13), 1,4-di(ethynyl)-2,5-di(n-hexyl)benzene (18), and 1,4-di(ethynyl)-2,5-di(n-propyl)benzene (19). These building blocks were reacted with α,ω-dithiocyanato-n-alkanes and α,ω- diselenocyanato-n-alkanes with n = 3-6. In the case of 10 also 1,1′-di(2-thiocyanatoethyl)cyclohexane (24) was reacted to afford a cyclophane comprising three subunits of 11. From most of the resulting macrocyclic cyclophanes (4(n) (n = 3, 5), 5, 6, 7(n), 8(n) (n = 3-6), 9(n) (n = 3, 5), and 10), we were able to grow single crystals. The X-ray analysis of 4(3), 7(3), 8(3), 8(4), 6, 7(5), and 8(5) revealed close contacts between the chalcogen atoms. These chalcogen-chalcogen interactions impose a ribbon-shape arrangement of molecules in 4(3) and a mutual crossing of two perdendicular planes built of 8(4) molecules. For 4(3) we found a close contact (3.28 A) between the π planes of two neighboring C6H4 rings of different molecules, whereas in 8(4) such a close contact (3.74 A) was due to an intermolecular interaction. Tubular stacking of the macrocyclic rings was found for 7(5) and 8(5) caused by a ladder-type intermolecular chalcogen-chalcogen interaction.
