<Junichi Uenishi> developed a selective route from gem-dibromoalkenes to geometrically pure (Z)-bromoalkenes. The <palladium>-catalysed hydrogenolysis removes one <bromine> substituent while controlling the geometry of the remaining carbon–carbon <double bond>.<A general and convenient synthetic method of geometrically pure (Z)-1-bromo-1-alkenes by Junichi Uenishi and others>[1996, pp.6759–6762: selective palladium-catalysed hydrogenolysis]{ref}
