1-(4-Formyl-2,6-dimethoxyphenoxy)-4-chlorobut-2-yne

Dataset
Disciplines : chemistry, organic
Collected date : from 2020 to 2021
Creators : Jérôme Husson

A reaction of biomass-derived aldehyde synringaldehyde and half an equivalent of 1,4-dichlorobut-2-yne was attempted in order to obtain a bis-aldehyde with an alkyne spacer. The reaction was carried out in a basic media to effect bis O-alkylation, as described in literature for the preparation of ...

4′-(5-Methylfuran-2-yl)-2,2′:6′,2″-terpyridine: A New Ligand Obtained from a Biomass-Derived Aldehyde with Potential Application in Metal-Catalyzed Reactions

The new ligand 4′-(5-methylfuran-2-yl)-2,2′:6′,2″-terpyridine (1) was prepared in one step from 2-acetylpyridine and 5-methylfurfural. The latter is an aldehyde that can be readily obtained from biomass. The new terpyridine molecule was characterized by 1H and 13C-NMR spectroscopy as well as by ...

Control of Structures and Emission Properties of (CuI)n 2-Methyldithiane Coordination Polymers

A structurally unique and strongly luminescent nonporous 3D coordination polymer (CP) [Cu8I8(methyldithiane)4]n, CP3, has been prepared in a quasi-anticipated manner from 2-methyl-1,3-dithiane, L1, and CuI. This CP incorporates an unprecedented Cu8I8 cluster built upon two side-fused open cubanes. ...

A Fused Poly(truncated rhombic dodecahedron)-Containing 3D Coordination Polymer: A Multifunctional Material with Exceptional Properties

The design of new and inexpensive metal-containing functional materials is of great interest. Herein is reported a unique thermochromic near-IR emitting coordination polymer, 3D-[Cu8I8(L1)2]n, CP2, which is formed when ArS(CH2)4SAr (L1, Ar = 4-C6H4OMe) reacts with 2 equiv of CuI in EtCN. In MeCN, ...

Crystal structure of di-[mu]-iodido-bis­[bis(aceto­nitrile-[kappa]N)copper(I)]

The title compound, [Cu2I2(CH3CN)4], exhibits a centrosymmetric Cu2I2 core [Cu...Cu distance = 2.7482 (11) Å], the CuI atoms of which are further coordinated by four mol­ecules of aceto­nitrile. The CuI atom has an overall distorted tetra­hedral coordination environment evidenced by L-Cu-L angles (L ...

Dataset
Disciplines : chemistry, organic
Collected date : from 2018 to 2019

A new pyrrole-substituted terpyridine derivative that possesses an allene moiety was obtained as an “unexpected” sole product during an attempt to alkylate the N-atom of pyrrole with propargyl bromide in order to obtain an alkyne-functionalized terpyridine.
