, p. 3501 - 3504 (1982)
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).
CHIRAL RECOGNITION OF ALLENIC HYDROCARBONS BY 1H NMR

, p. 399 - 408 (2007/10/02)
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)
