Two Pd-catalyzed C–N bond-forming reactions are included in the text as representative examples of these procedures. Although the reactions can proceed in <5 min, the protocols, including workup ...

recently discovered the first example of base metal catalyzed regioselective and direct ... they proposed a plausible reaction mechanism (Scheme 2), which involves a Cu(III) intermediate.

X-ray crystallography of enzyme-substrate or enzyme-substrate analog complexes has since produced detailed examples of how enzymes recognize and bind substrates. Many enzymes catalyzed reactions ...

demonstrating that the catalyst was not consume in the reaction. Goggles should be worn. Wear gloves when handling 30% hydrogen peroxide. Watch out for spattering during the catalyzed reaction.
