Allylic rearrangement in reactions of acetylenic compounds with allyl and benzyl derivatives of boron

Conclusions The reaction for the addition of crotyl and benzyl derivatives of boron to alkoxyacetylenes proceeds with a rearrangement of the allylic type. On alcoholysis, the vinylboranes that are formed here give derivatives of either the 2-alkoxy-1,4-pentadiene or the-alkoxystyrene.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 11, pp. 2631–2634, November, 1970.
