The thermal and anionic rearrangements of substituted 1-vinyltrans-
cyclotridec-3-en-l-ol compounds have been studied to determine
what effects substituents would have on the sigmatropic shift when
placed on the two positions of the 1-vinyl group.
For the thermal rearrangements, the a-substituted vinyl-trans-cyclotridecenols
gave both the [3,3] and [1,3] shift products of...
A study of the effects of structural modification at
the alpha position of ethyl 2-bromocarboxylates on their
rates of addition to two alkene pairs was undertaken. In
the competition between 3-propoxypropene and 1-octene at
70°, a 37% increase in selectivity was observed in going
from carboxylates generating primary radicals to...
