4′-(N-(Propargyl)pyrrol-2-yl)-2,2′:6′,2′′-terpyridine
A new terpyridine molecule, bearing a N-propargylated pyrrole, was prepared and characterized. Its synthesis was based on a Krohnke-type reaction between 2-acetylpyridine and N-propargylpyrrole-2-carboxaldehyde in a basic medium. An allene-containing terpyridine was also obtained as a by-product.
1-(4-Formyl-2,6-dimethoxyphenoxy)-4-chlorobut-2-yne
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
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),...
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
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
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 ...
