The vibrational properties of a series of push-pull polyynes have been studied by infrared and Raman spectroscopy. The simultaneous activation of a strong infrared and Raman mode, i.e. the collective vibration of CC bonds of the sp carbon chain, high

A series of meta-phenylene-butadiynylene macrocycles was obtained by homocoupling of terminal bis(ethynyl) precursors using Eglinton conditions. Cyclotetramers and cyclopentamers were isolated from the mixture. However, a hexameric analogue was synth

A solvent-free coupling of azulenes with 1-haloalkynes and 1-halopolyynes has been developed. 1-Haloalkynes were used as substrates and the reaction needs only simple grinding of substrates in a mortar with basic Al2O3 without solvents or precious me

Synthesis of complex di(selenophen-3-yl)diselenides and 3-methylene-3H-1,2-diselenoles directly from 1-bromobutadiynes is described. The transformation is performed under conditions used before for the synthesis of simple selenophenes from butadiynes

The first planar π‐extended azulene that retains aromaticity of odd‐membered rings was synthesized by [3+3] peri‐annulation of two naphthalene imides at both long‐edge sides of azulene. Using bromination and subsequent nucleophilic substitut

Here we report a new palladium-catalysed [3 + 3] annulation method for the synthesis of polycyclic aromatic hydrocarbons (PAHs) from two smaller aromatic fragments. The successful application to various perylene derivatives is demonstrated based on o

Polyynes are compounds with two or more conjugated carbon–carbon triple bonds. Such molecules are usually regarded as models of carbyne—a hypothetical one-dimensional allotropic form of carbon. 1-Halopolyynes are rare representatives of such spec
