Configurational stability of propargyl zinc reagents

According to the <<Hoffmann test>>, allenylzinc bromides derived from allenyllithium have been reacted with racemic and non-racemic alpha -alkoxy-imines at various temperatures. The ratio of the diastereomeric alpha -aminoethers thus obtained points to an appreciable configurational stab...

Summary:According to the <<Hoffmann test>>, allenylzinc bromides derived from allenyllithium have been reacted with racemic and non-racemic alpha -alkoxy-imines at various temperatures. The ratio of the diastereomeric alpha -aminoethers thus obtained points to an appreciable configurational stability of the organometallics.
