The thermodynamic stability of these compounds increases with substitution; thus, highly substituted ones are favored in eliminations according to Zaitsev's rule.
Compounds containing two of this functional group in a 1,5-pattern can interconvert in a [3,3]-sigmatropic rearrangement. In the "conjugate addition" of soft nucleophiles, this functional group is added beta to a carbonyl group. The reaction of phosphonium ylides with ketones or aldehydes favors the production of the Z-stereoisomer of these compounds. Because they rapidly decolorize liquid bromine, bromine can be used to test for their presence. The thermodynamic stability of these compounds increases with substitution; thus, highly substituted ones are favored in eliminations according to Zaitsev's rule. For 10 points, name this functional group that consists of two sp2-carbon atoms linked together by a double bond.
