Olefin isomerization by a ruthenium carbenoid complex. Cleavage of allyl and homoallyl groups

Ruthenium-carbenoid catalysts such as Grubbs' complex I mediate efficiently the isomerization of beta,gamma-unsaturated ethers and amines to the corresponding vinyl ethers and enamines. This reaction can be useful in the deprotection of allyl and homoallyl ethers as well as amines. (C) 2002 Elsevier Science Ltd. All rights reserved.
