Abstract
Bromine/lithium exchange was performed upon treatment of alpha-bromo-v inylic chalcogenides with butyllithium in hexane at room temperature t o provide alpha-chalcogen-vinyllithium intermediates quantitatively. A ddition of electrophiles to the lithiated compounds gave the correspon ding functionalized vinylic chalcogenides in good yields with retentio n of configuration.
