The simplest enone is methyl vinyl ketone ( butenone ) or CH 2 = CHCOCH 3.
2.
Methacrolein is one of two major products resulting from the reaction of isoprene with OH in the atmosphere, the other product being Methyl vinyl ketone ( MVK, also known as butenone ).
3.
The reaction of cyclopentadiene and butenone for example is 700 times faster in water relative to 2, 2, 4-trimethylpentane as solvent . or hydrogen-bond stabilization of the transition state.
