Fluordiazadiphosphetidine, 18. Mitt. Neue zwitterionische Fluordiazadiphosphetidinderivate
Autor: Klaus Galle, Kurt Utvary
Publikováno v: Monatshefte f�r Chemie Chemical Monthly. 119:53-63
The reaction of (CH3NPF3)2 with substituted hydrazines yields a new type of a P/N/P/N ring system by addition of one molecule hydrogenfluorid to the substituted molecule. These betain-like compounds are the first examples of a P/N/P/N ring system wit
