An Unprecedented Intramolecular Migration of Carbon Groups from Aluminum to an Adjacent Vinylic Center and Its Application to the Synthesis of Stereodefined Olefins
Miller, Joseph A.

Hydroalumination of 1-chloro-1-alkynes by sodium trialkylaluminum hydrides furnishes stereo- and regioselectively the respective (E)-1-chloro-1-alkenylalanates, which, in the presence of NaOMe, undergo a novel 1,2-migration of a carbon group from Al to the adjacent vinylic center to generate a useful synthesis of di- and trisubstituted olefins of defined geometry.
DIOLS AS EFFECTIVE COCATALYSTS IN THE PHASE TRANSFER CATALYZED PREPARATION OF 1-ALKYNES FROM 1,2-DIHALIDES

Bis-tertiary diols accelerate bis-eliminations of HX from 1,2-dihalides in the presence of an onium salt as phase transfer catalyst and potassium hydroxyde as base.PEG 400 catalyzes the same elimination, but isomerizations from 1-alkyne to mixtures with the 2-alkyne and the 1,2-diene occur easily.
