The First Stable Arsaphosphaallene, ArPCAsAr

The first arsaphosphaallene, ArPCAsAr (1; Ar = 2,4,6-tri-tert-butylphenyl), has been synthesized by debromofluorination of the (phosphaalkenyl)fluoroarsane 5 by n-butyllithium at low temperature and characterized by NMR (δP +159.7 ppm, δC +299.5 ppm) and X-ray analysis. A 1H NMR study between +55...

Description
Summary:The first arsaphosphaallene, ArPCAsAr (1; Ar = 2,4,6-tri-tert-butylphenyl), has been synthesized by debromofluorination of the (phosphaalkenyl)fluoroarsane 5 by n-butyllithium at low temperature and characterized by NMR (δP +159.7 ppm, δC +299.5 ppm) and X-ray analysis. A 1H NMR study between +55 and −60 °C allowed the determination of the rotation barrier of Ar groups.
