Die Reaktion eines gemischten Doppelylids mit Ethylenoxid / Reaction of a Mixed Double Ylide with Ethylene Oxide

Abstract

Abstract Dimethyl-trimethylphosphinimino-methylene-phosphorane, (CH3)3P=N-P(CH3)2 = CH2 was found to react with ethylene oxide to form a 1:1 adduct, that was identified as 2,2-dimethyl-2-trimethylphosphinimino -1,2λ5 -oxaphospholane. According to its 1H, 13C, 31P NMR spectra it is assigned a rigid trigonal bipyramidal structure with nitrogen and oxygen atoms in axial positions.
