Номер: US20050033094A1
Автор: Clinton Boriack, Zeng Liao
Принадлежит: Boriack Clinton J., Liao Zeng K.

A process for preparing an allyl ether including reacting (a) a phenolic compound with (b) an allyl carboxylate or an allyl carbonate in the presence of (c) a transition metal or rare earth metal catalyst complexed with at least one strongly bonded, non-replaceable stable ligand whereby an allyl ether is formed. The ligand of the transition metal or rare earth metal catalyst complex may be (i) an olefinic-containing ligand or aromatic-containing ligand; or (ii) a polymeric ligand or a heteroatom-containing multidentate ligand.
