The syntheses of the allenes (+/-)-1, (+/-)-4, and (+/-)-6 as well as of the enriched samples (-)-1, (-)-4 and (-)-6 are described. 1H NMR shifts and splittings induced by a mixture of the achiral salt Ag(fod) and the optically active complex (+)-Yb(hfbc)
MECHANISMES DE LA PROTONOLYSE DES ORGANO-CHROMIQUES ISSUS DE BROMURES PROPARGYLIQUES.

The reaction of CrCl2 with propargylic bromides leads to an allenic organo-chromic derivative protonated without rearrangement by carboxylic acids.Alcohols like menthol transform this metallic to its propargylic isomer and then protonate it with rearrangement(SEi' type mechanism).
