Abstract
The conjugate base of ntacarbonyl(propenylpyrrolidinocarbene)chromium( 0) is easily generated at -78 degrees C with LDA and reacts with elect rophilic reagents to provide the corresponding addition products in sa tisfactory to good yields. The alpha/gamma regioselectivity depends on the nature of electrophile and is also discussed in comparison with t he behavior of the anions of crotonamides
