✦ Synopsis

C,H:' ions generated from ionized n-butanol (a) and from ionized Zmethylpropanol (b) were characterized by reaction of the daughter ions with ammonia in a Fourier transform mass spectrometer. Hydrogen transfers occur in a in the ratio five-membered ring:six-membered ring = 1:3.2. However, both hydrogen-transfers are followed by the formation of ionized methylcyclopropane. Ionized methylcyclopropane is also produced on elimination of water from b. CH,-(CH,)n CH,-(CHz), yy' + HY CHz-(CHz), CH,-NH, + C \ m/z44 6 %I CH,CH,NH, + * mlz 45
