Article abstract of DOI:10.1016/0040-4039(91)80875-7

Oxime O-allyl ethers are equilibrated with the corresponding N-allyl nitrones on treatment with 10 molpercent PdCl2(MeCN)2 by a formal <2,3>-sigmatropic shift.The nitrones can be trapped both inter- and intra-molecularly by appropriate dipolarophiles to g
