Zusammenfassung:
Compounds containing carbon-carbon double bonds bearing cis deuterium atoms can be prepared conveniently by treating disubstituted acetylenes with bis(2-deuteriocyclohexyl)borane-B-D-1 [DB(Cy)(2)] followed by reaction with CH3CO2D. As an example, the preparation of labeled linolenic acid is reported.
