Suggest a synthesis of 1, using as starting materials the Her o CO,Et es -CHO 4. a) Lily aldehyde (1) is an ingredient used in perfumery. Suggest a synthesis of 1, using as starting materials, the ester 2 and 1-propanol. You may use any other applicable inorganic and/or organic reagents, but LiAIH, NaOH (aq). PCC, H2, DIBAL, and Pd/C are the most likely choices (depending on your synthetic route). No reaction mechanism(s) is required. Lily aldehyde b) Using 2-methyl-1,3-cyclopentanedione, acetaldehyde...

Label each line chemical reaction in terms of the meaning in how a catalyst increases the rate or a chemical reaction in terms of the Explain how a cada of...
Draw a pathway for the reaction of phenylboronic acid with 4-iodophenol to obtain 4-phenylphenol in the form of a catalytic cycle. EXPLAIN and STATE all complexes formed in EACH STEP by their electron counts (count how many e- are there, e.g. 18 e- or 16 e- etc.), formal oxidation states and all the reactions with mechanistic labels (i.e. oxidative addition, reductive elimination, etc.) (note the amount of base used). Be sure to EXPLAIN the catalytic cycle as to what happens...
