Fritsch-Buttenberg-Wiechell rearrangement in the aliphatic series
[reaction: see text] Substituted vinylidene zinc carbenoids undergo a Fritsch-Buttenberg-Wiechell rearrangement. The migratory aptitude of the two groups R/R1 was studied by 13C labeling experiments and depends on the degree of substitution in R and R1 groups and on the presence of an oxygen atom in the allylic position.
