Abstract

The molecular ions of the title compounds appear to lose a benzyl radical, which must be due to the presence of two benzyloxy groups, as benzylalkyl ethers do not exhibit such an expulsion upon electron impact. The results of the partition of the labels deuterium and 18O in the ions m/e 107 (protonated benzaldehyde) and [M-benzyl-benzaldehyde]+ put forward evidence that this process is initiated by a successive migration of a benzylic H atom to the ...
