  Organic chem- a reaction a day   Awaiting Review for Nickels
Tagged with:          [Post New]posted on 9 Feb 2008 14:29:04 IST    
The reaction for the day

Michael Addition

The 1,4-addition (or conjugate addition) of resonance-stabilized carbanions. The Michael Addition is thermodynamically controlled; the reaction donors are active methylenes such as malonates and nitroalkanes, and the acceptors are activated olefins such as ?,?-unsaturated carbonyl compounds.
Examples:
donors
acceptors
