Show how you would accomplish the following synthetic conversions efficiently and in good yield. You may use any necessary additional reagents and solvents.
- The cyclopentanone reacts with phosphorus ylide to form an alkene.
(b) Anisole reacts with CO and HCI in the presence of to form 2-methoxybenzaldehyde.
(c) The (2-bromo ethylene) cyclopentene reacts with KCN to form 3-cyclopentylidene propanenitrile.
(d) The phosphorus ylide reacts with cyclopentanone to form an alkene.
(e) The hydrate loses water molecule to form 1-phenylprop-2-en-1-one.
(f) The lactone can be reduced to tetrahydrofuran-2-ol. It undergoes hydrolysis to form an aldehyde.
(g) The hydrate lossed water molecule to form a ketone.
(h) The 4-acetyl benzaldehyde reacts with phosphorus ylide to form an alkene.
