Unformatted text preview: do you think there
is a change in reactivity for the sulfur vs. the phosphonium ylide?
On Friday (3/3/11), we will learn more about α,β-unsaturated carbonyl compounds. After Friday’s lecture,
explain the difference in reactivity below. Be sure to include the correct arrow-formalism for each
O O O (H3C)2HS CH2 (H3C)2S ! CH2 O + DMSO O 3. Provide the correct arrow-formalism for the following iodolactonization reaction. Recall how halogens
react with alkenes.
CH3 CH3 H 3C O
CH3 I 2
