摘要：
The conjugate base of pentacarbonyl(propenylpyrrolidinocarbene)chromium(0) is easily generated at -78 degrees C with LDA and reacts with electrophilic reagents to provide the corresponding addition products in satisfactory to good yields. The alpha/gamma regioselectivity depends on the nature of electrophile and is also discussed in comparison with the behavior of the anions of crotonamides
