Isomerization processes in the synthesis of asymmetric allyl chalcogenides

摘要

Allyl-propenyl rearrangement (prototropic isomerization) occurs in the synthesis of allyl organyl chalcogenides in a hydrazine hydrate-KOH system with a 6–10-fold molar excess of KOH. Specificities of the rearrangement that depend on the nature of the chalcogen were studie
