The metastable peaks appearing in a mass spectrum give a direct measure of the kinetic energy released in the dissociation of an ion. ' Overlapping isotope peaks; the value given is a lower limit for the KE release

Tertiary alcohols with a y-silyl group (3) generally undergo a simple carbonium ion rearrangement in acid giving a single alkene product (4) with loss of the silyl group. We reported earlier several examples of carbonium ion rearrangements of the general type (1 + 2) in which the migrating group R
## Abstract The polymerization of olefins of the series (__n__β1)methylβ1βalkenes through carbonium ion intermediates appears to involve a rearrangement from a secondary to a tertiary carbonium ion. The structure of the final polymer, as determined by nuclear magnetic resonance, depends on the rela
Formation of acyclic products in the reaction of triisobutylaluminum and 1,3,3trimethylcyclopropene can reasonably be ascribed to a carbonium ion rearrangement. This suggestion supports the mechanism for carbalumination of alkenes proposed by Eisch.
