Abstract:
A fast atom bombardment (FAB) mass spectrometric study on the open‐chain compound 1,3‐bis(cyanomethylenetriphenylphosphorane)propane‐1,3‐dione and on the cyclic zwitterionic compounds 4‐oxy‐5‐triphenylphosphonium‐6‐methyl‐2‐pyrone and 4‐oxy‐5‐triphenylphosphonium‐6‐phenyl‐2‐pyrone, obtained by reaction of carbon suboxide, C 3 O 2 , with stabilized phosphorus ylides, Ph 3 PCHX (XCN, COMe, COPh), is described. The FAB mass spectrometric behaviour of these compounds is compared with that shown by tri‐phenylphosphoranilideneketene, Ph 3 P C C O, and by 4‐hydroxy‐6‐methyl‐2‐pyrone, with the aid of metastable ion data and collision spectroscopy.
