Meng, Genyi published the artcileModular click chemistry libraries for functional screens using a diazotizing reagent, Application of 2,2-Dimethoxyethanamine, the main research area is alkyl aryl azide triazole chemoselective preparation; fluorosulfonyl azide generation chemoselective diazotization primary amine; combinatorial generation library alkyl aryl azide cycloaddition alkyne; functional screen click chem azide generated in situ.

Alkyl and aryl azides were prepared from the corresponding primary alkyl and aryl amines by reaction with fluorosulfonyl azide generated in situ from a fluorosulfonylimidazolium triflate and sodium azide, expanding access to azides and both to the 1,2,3-triazoles derived from them and to functional screens employing them. The method allowed the preparation of a library of >1000 azides from the corresponding amines; the azide library underwent copper-catalyzed azide-alkyne cycloaddition reactions to yield a library of >1000 1,2,3-triazoles.

Park, Hea Jung published the artcileNew blue phosphorescent heteroleptic Ir(III) complexes with imidazole- and N-methylimidazole carboxylates as ancillary ligands, Computed Properties of 22483-09-6, the main research area is spirocyclic phenylpyridinyl iridacycle imidazolecarboxylate preparation electrochem OLED phosphorescence; crystal structure spirocyclic phenylpyridinyl iridacycle imidazolecarboxylate; mol structure spirocyclic phenylpyridinyl iridacycle imidazolecarboxylate.

Imidazole- and N-methylimidazole carboxylate were introduced to serve as ancillary ligands in heteroleptic Ir(III) complexes containing 2-phenylpyridine-based main ligands, with consideration of the frontier orbital energy levels. Complexes Ir1-Ir4 were synthesized and found to have LUMO levels higher than that of the corresponding Ir(III) complex containing pyridyl carboxylate. All the synthesized Ir(III) complexes exhibited blue phosphorescence emission maxima at 465-467 nm at room temperature Phosphorescent quantum efficiencies were increased by a factor of 1.8-6.7 by blocking the intermol. H bonding between the imidazole carboxylate ligands of neighboring Ir(III) complexes, which was achieved by N-methylation of the imidazole carboxylate ancillary ligand. The organic light-emitting diodes fabricated using Ir3 and Ir4 as dopant materials in the emissive layers emit blue emission with peaks at 469 and 471 nm and maximum external quantum efficiencies of 20.0 and 22.4%, resp. Also, all the fabricated devices with Ir3 and Ir4 exhibited low efficiency roll-off, indicating excellent stability of the materials.

Kohlmeyer, Corinna published the artcileFormamide-Catalyzed Nucleophilic Substitutions: Mechanistic Insight and Rationalization of Catalytic Activity, Recommanded Product: 2,2-Dimethoxyethanamine, the main research area is formamide catalyzed nucleophilic substitution mechanism.

Herein, detailed mechanistic investigations into formamide-catalyzed nucleophilic substitution (SN) of alcs. are reported. Alkoxyiminium chlorides and hexafluorophosphates were synthesized and characterized as a key intermediate of the catalytic cycle. The determination of reaction orders and control experiments indicated that the nucleophilic attack of the formamide catalyst onto the reagent BzCl is the rate-determining step. Linear free energy relationship revealed a correlation between the quantified Lewis basicity strength of formamides by means of 11B NMR spectroscopy and their catalytic activity in SN-transformations. The observed difference in catalytic ability was attributed to the natural bond order charge, dipole moment, and Sterimol parameter B5. Importantly, this rationalization enables the prediction of the capacity of formamides to promote SN-type transformations in general.
