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

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′-(N-(Propan-1,2-dienyl)pyrrol-2-yl)-2,2′:6′,2″-terpyridine

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.

Crystal structure of {μ2-1,2-bis­[(4-methyl­phenyl­sulfan­yl]-3-oxoprop-1-ene-1,3-di­yl-1:2κ2C3:C1}dicarbon­yl-1κ2C-[μ2-methyl­enebis(di­phenyl­phos­phane)-1:2κ2P:P′](tri­phenyl­phosphane-2κP)iron­platinum(Fe—Pt),...

Disciplines : crystallography
Collected date : from 2017 to 2020

The title compound, [FePt(C19H18OS2)(C18H15P)(C25H22P2)(CO)2], 1, [(OC)2Fe(μ-dppm)(μ-C(=O)C(CH2SC6H4Me-4)=CCH2SC6H4Me-4)Pt(PPh3)], represents the first example of a diphosphane-bridged heterobimetallic Fe—Pt dimetalla­cyclo­pentenone complex resulting from a bimetallic activation of ...

Synthesis of Tris(arylphosphite)-ligated Cobalt(0) Complexes [Co2(CO)6{P(OAr)3}2], and their Reactivity towards Phenylacetylene and Diphenylacetylene

Disciplines : crystallography
Collected date : from 2018 to 2020

The dinuclear complexes [Co2(CO)6{P(OAr)3}2] (1a, Ar = Ph; 1b, Ar = o-Tol) were prepared and reacted with PhC≡CH and PhC≡CPh to yield dimetallatetrahedranes [{(ArO)3P}(OC)2Co-Co(μ-RC≡CPh)(CO)2{P(OAr)3}] (3a, Ar = Ph, R = H; 3b, Ar = o-Tol, R = H; 3c, Ar = Ph, R = Ph; 3d, Ar = o-Tol, R = Ph). The ...

3-spiroindolizines containing an isoindole ring through intra-molecular arylation of spiro-N-acyliminium species

Collected date : from Jan 2017 to Oct 2018

Based on N-acyliminium species, efficient approaches to spirocyclic systems connected by two different carbon centers to the isoindole ring have been developed. The imide reduction and the tandem oxidative cleavage of olefin/formyl-amide equilibration were at first selected as the key steps for ...
