摘要：

The addition of allylic barium reagents to azo compounds was achieved with high alpha-regioselectivity. The double-bond geometry of allylic barium reagents was retained throughout the reaction at -78 degrees C and E- or Z-enriched allylic hydrazines were selectively obtained from the corresponding allylic barium reagents. An allylic hydrazine was efficiently converted into an allylic amine by reductive N-N bond cleavage.
