The reaction of acetylated α-allenic alcohols with LiBr in the presence of 1.5 mol % of Pd(OAc)2 provides easy access to substituted (Z,E)-2-bromo-1,3-dienes in good yields with excellent diaste-reoselectivity. Both secondary and tertiary acetates as well as terminal and nonterminal allenes were studied to investigate the scope and the limitations of the reaction. A mechanism is proposed to clarify how a diastereomeric mixture of the starting compound is transformed into a single diastereomer of the product.
Gold catalysis: Evidence for the in-situ reduction of gold(III) during the cyclization of allenyl carbinols

Products of an oxidative coupling were obtained in the gold(III)-catalyzed cycloisomerization of tertiary allenyl carbinols. The absence of reduced organic products and an increase of these coupling products with the amount of gold(III) catalyst suggests
