E alkene from E/Z-mixture

Posted by naturalproductman on July 7, 2011

Ever want to selectively isolate the E-isomer of a E/Z-mixture of alkenes?  Well Hoveyda and Schrock have reported in JACS on the use of a molybdenum catalyst (monoaryloxide-pyrrolide – ie:  MAP – complex with molybdenum) in the presence of ethylene to completely abolish the Z-alkene from the mixture via ethenolysis.
