Abstract

original image

The first cyclopentadienylboranes having boron in allylic position to the ring have now been prepared. The vinylic isomers (2), otherwise always formed preferentially, cannot arise from (1) and its derivatives because the activation energy of the 1,2-methyl shift is too high.
