Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application

European Journal of Organic Chemistry, EarlyView.
Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

Manganese-containing mixed oxide electrodes as anode materials for degradation of model organic pollutants [PDF]

, 2017
Mixed oxide thin film electrodes have been prepared by thermal decomposition from alcoholic solution on Pt substrate. In particular, three different anodes have been obtained by co-deposition of Ru (Ruthenium) and Mn (Manganese) oxides, Ru, Mn and Cu ...

Original Reactivity of ?-Diazo-?- ketoesters Catalyzed by CpRu Complexes

CHIMIA, 2014
Using ?-diazo-?-ketoesters as reagents and combinations of CpRu fragments and diimine ligands as catalysts, a series of original transformations have been obtained that can be rationalized by the formation of metal carbenes and metal-bound ylide

C–H insertion as a key step to spiro-oxetanes, scaffolds for drug discovery [PDF]

, 2017
A new route to spiro-oxetanes, potential scaffolds for drug discovery, is described. The route is based on the selective 1,4-C–H insertion reactions of metallocarbenes, generated from simple carbonyl precursors in flow or batch mode, to give spiro-β ...

Rh(III)‐Catalyzed [4+2] Annulation of Imidazoles With α‐Diazocarbonyl Compounds: Direct Access to π‐Conjugated Imidazole‐Fused Isoquinolinone

European Journal of Organic Chemistry, EarlyView.
A Rh(III)‐catalyzed [4 + 2] annulation of 2‐aryl imidazoles/benzimidazoles with α‐diazocarbonyl compounds is developed for the synthesis of π‐conjugated imidazo/benzimidazo[2,1‐a]isoquinolinones systems. Mechanistic studies and control experiment reveal that the reaction proceeds via imidazole‐directed ortho C(sp2)–H activation, followed by carbene C–H

Triphenyl{(E)-4-[4-(phenyldiazenyl)phenyl]-4H-1,2,4-triazol-1-yl}boron

Acta Crystallographica Section E, 2009
In the title compound, C32H26BN5 or [(C14H11N5)B(C6H5)3], the B atom is approximately tetrahedrally coordinated. The diazo unit is in a trans conformation, which is generally more stable than a cis one for aromatic azo compounds.
