Luminescence Vapochromism of a Cu(I)/Na Phosphane Iodide Assembly Based on a Secondary‐Sphere Sodium Response

Angewandte Chemie, EarlyView.
The luminescence of a heterometallic d‐s {Cu2I2Na2} phosphane‐phosphinate aggregate is regulated by an interplay of Na+–π/I– contacts and reversible coordination of oxygen‐containing organic molecules to Na ions. Structural variations caused by the incoming guest lead to a wide and selective variation of the emission color and illustrate a new approach

1,2,4-Oxadiazoles from cycloreversions of oxadiazabicyclo[3.2.0]heptenes: 1-azetines as thiocyanate equivalents [PDF]

, 2013
1,3-Dipolar cycloaddition of nitrile oxides to 4-aryl-2-alkylthio-1-azetines gave a series of oxadiazabicyclo[3.2.0]heptenes as single diastereoisomers. Heating these cycloadducts in toluene resulted in an overall [2+2]-cycloreversion to give 5-alkylthio-

Die Aza‐Büchner–Curtius–Schlotterbeck‐Reaktion: Selektive Bildung Quartärer Kohlenstoffzentren

Angewandte Chemie, EarlyView.
Wir stellen die Aza‐Büchner–Curtius–Schlotterbeck‐(ABCS)‐Reaktion vor: eine milde, katalysatorfreie Methode zur Homologierung von Aryliminen. Im Gegensatz zum traditionellen BCS‐Mechanismus durchläuft das Diazo‐Intermediat eine selektive C─C‐Insertion zur Bildung eines quartären Zentrums.

Atroposelective Pd(0)‐Catalyzed Direct Intermolecular C─H Arylation of Thiazole N‐Oxides Provides Access to Heterobiaryls

Angewandte Chemie, EarlyView.
An enantioselective Pd(0)‐catalysed arylation at the C4‐position of thiazole N‐oxides directly forges the atropochiral heterobiaryl axis. A tailored point‐ and axially chiral monodentate phosphine ensures high reactivities along with a tight stereocontrol.
