Abstract

Er(OTf)3 is a useful catalyst for the Ferrier rearrangement furnishing high yields of products, cleaner reaction profiles, short reaction times, mild reaction conditions, high stereoselectivity and recoverability of the catalyst which is also commercially available.

The purity of recovered Er(OTf)3 was confirmed by comparison with the IR spectrum of commercial product.
