摘要
A very simple, convenient method for an efficient shape-selective isomerisation of acyclic and aromatic alpha-acetylenic alcohols only, to the corresponding alpha,beta-ethylenic carbonyl compounds, leaving the cyclic ones unreacted using catalytic amounts of vanadium-pillared montmorillonite catalyst, having -Si-O-V = 0 groups with successful reusability is described.
