Sn(Bu)3 Pd(PPhz)4 (cat.), toluene, reflux Br N Br (i) Provide a mechanism for the Pd(0) catalyzed cross-coupling reaction between 7 and 8 that details the complete catalytic cycle for a single substitution process.
draw the catalytic cycle for the formation of 4-phenylphenol
via this suzuki reaction. please write out full compounds in the
diagram and not just R1,R2, etc. it should include oxative
addition, transmetallation, reductive elimination abd regeneration
of Pd(0), and rationale for the quantity of base used.

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...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
