It was found that the silver salt and base was an efficient catalytic system for the reaction of the secondary propargylic alcohol with carbon dioxide to afford various corresponding vinylene carbonate derivatives in good to high yields under mild conditions. Georg Thieme Verlag Stuttgart New York.
Studies on Cu(I)-catalyzed synthesis of simple 3-substituted 1,2-allenes and optically active 2-substituted secondary 2,3-allenols

experimental part, p. 3695 - 3703 (2009/09/05)
The sequential treatment of terminal alkynes or propargylic alcohols with n-BuLi and MOMCl afforded the corresponding propargylic methyl ethers, which would react with primary alkyl Grignard reagents under the catalysis of CuBr to afford 3-substituted 1,2-allenes or 2-substituted secondary 2,3-allenols, respectively. The reaction may be applied to the synthesis of optically active 2-substituted secondary 2,3-allenols with up to >99% ee without any protection to the free hydroxyl group in the starting 4-hydroxy-2-alkynyl methyl ethers.
Regiocontrol in Pd-catalyzed allylic substitution with P,N-ligand

, p. 97 - 100 (2007/10/03)
A racemic ligand, (±)-N-[2-(diphenylphosphino)naphthyl]-2- (pyrrolidinylmethyl)piperidine, has been found to exhibit better regioselectivity than the racemic Pfaltz ligand, BINAP and dppp in the palladium-catalyzed regioselective allylic substitution with
