Synthesis of (E)-nitro olefins by isomerisation of (Z)-nitro olefins with polymer-supported triphenylphosphine
摘要:
We have found that (Z)-nitro olefins or mixtures of (E)- and (Z)-compounds can be converted to the pure (E)-isomers by treatment with catalytic amounts of triethylamine or polymer-bound triphenylphosphine, respectively. (C) 1998 Elsevier Science Ltd. All rights reserved.
