Cat. II
or reactant R2
is added
after R1
is completly converted to
intermediate R1'
All reactants and catalysts are added in
one pot. Intermediate R1'
is subsequently
consumed in the next catalytic cycle.
All reactants and catalysts are added in
one pot. Reactants are simultaneously
activated by distinct catalysts.
