✦ Synopsis

Metal(1) hydrides are eliminated as neutral species in the electron impact ionization mass spectra of copper(II) and palladinm(1I) complexes of ethylene-N,N-3-benzoylprop-2-en-2-amine. Deuterium labelling shows that the hydrogen atom of the metal(1) hydride is derived predominantly from the ethylene bridge both for ion source reactions and for metastable ion transitions. Evidence supporting the proposed rationalization for elimination of metal(1) hydride i s provided by the observation of an analogous reaction in the mass spectrum of (ethylene-N,N-salicylaldiminato)copper(II). The mass spectrum of ethylene-d,-N,N-3benzoylprop-2-en-2-amine shows an nnusual rearrangement to give [C7HSD2]+ ions involving a formal phenyl-to-methylene transfer. 003(r493X/78/00 13-0 188%02.00

The most prominent ion in the mass spectra of C,F,CH,X (X = H, Br, CH:CH,, COCI, and CH,C6F5) is C,F5H2+, formulated as the pentafluorotropylium cation. This ion is also found, in an amount comparable to the parent ion, in the spectrum of (CBF5)\*CH2. The heptafluorotropylium cation is found similar

## Abstract The mass spectra of aryl sulfonamides of some 2‐aminopyridines and 2‐aminopyrimidine show abundant peaks corresponding tothe loss of SO~2~ and HSO~2~ from the molecular ion. Evidence in favour of a cyclization‐elimination reaction involving bond formation between the pyridine ring nitro
