The question of benzyl vs tropylium structures for ions of the general formula XC7H6+ has received renewed attention recently in the electron impact mass spectra of nitrobenzyl compounds (l), bibenzyls (Z), benzyl phenyl ethers (1,3,4), and n-butylbenzenes (5). Evidence for benzyl ion structures has
The photocyclization reaction of phenyl vinyl sulfides to benzo[b]thiophenes was studied in our laboratory by Groen, Kellogg, Buter and Wynberg (1).
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
