Chapter 21, Problem 1LGP

In “The Chemistry of... Complex Cross Couplings” we showed a Heck reaction used in the synthesis of ecteinascidin 743, a natural compound with anticancer activity isolated from the marine tunicate Ecteinascidia turbinate. Write a mechanism for this reaction, using P d L 2 to represent the palladium catalyst and abbreviating the complicated structures of the ecteinascidin synthetic intermediates as appropriate.

Propose a catalytic cycle for the reaction of an aldehyde with H2O to production of carboxylic acid and H2: Using the catalyst to follow the sequence of following stages in a cycle so that arrive at the original complex: (1) ligand substitution with aldehyde (2)migratory insertion (3) B-detachment (4) removal of product (ligand) (5) oxidative addition of H2O (6) reductive elimination of product (7) H2O ligand rearrangement Draw the mechanism steps
A scientist wants to look into the kinetics of the degradation of atrazine (A). There are 2 ways for degradation to occur. First, dealkylation to develop deisopropylatrazine (B) and deethylatrazine (C) with a kinetic constant of k1. Second, hydrolysis to create hydroxyatrazine (D) and N-isopropylammelide (E) with a kinetic constant k2. For all the mentioned species, derive their concentration profiles as a function of time when a batch reactor is utilized.
