Abstract
A number of years ago we revealed that preparation of the synthetically valuable a- haloalkenylboranes may be readily achieved through hydroboration of 1-halo-I-alkynes with dialkylboranes.'Unfortunately, attempts to synthesize the corresponding a- haloalkenylalanates via the reaction of 1-halo-1-alkynes with diisobutylaluminum hydride were unsuccessful.* However, since the trifunctional a-halovinylalanyl moiety represents a ...
