Radical cation promoted O-alkylation of oxime with N-vinyllactam was achieved under base free condition by using catalytic tris(4-bromophenyl)aminium cation radical (TBPA(+).SbCl6-) as an initiator to produce the corresponding oxime ether in high yields. (c) 2008 Elsevier Ltd. All rights reserved.

O-Alkylation of (E)- and (Z)-oxime was achieved via singleelectronoxidation of N-vinyl lactams by using a catalytic amount of tris(aryl)aminium salts as initiator, producing the corresponding oxime ethers in high yields under mild condition. A reaction mechanism based on electrontransfer was proposed.
