Notes:
Oxygen-alkyl cleavage is ruled out in the methane chemical ionization- and electron mpact-induced decomposition of cyclopropyl ethers by the finding that for trans,trans-2,3-diethylmethoxycyclopropane the [M — C2H5·]+ ion is more intense than the [M — CH3·]+ ion. The possibility for [M + H — C2H6]+ is discounted by comparison with the methane chemical ionization nass spectrum of tran,tran-2,3-dimethylmethoxycyclopropane. The isobutane chemical ionization nass spectrum of the diethylcyclopropyl methyl ether affords nearly exclusive electrocyclic methanol fragmentation, i.e. [M + H — CH3OH]+.
