(a)
Interpretation:
The substituted
Concept introduction:
In the Heck reaction, the palladium-catalyzed coupling of an aryl or vinyl halide with an alkene to give a new carbon-carbon bond at the less substituted end of the alkene, that are generally with trans stereochemistry.
This reaction is used in the drug synthesis; the palladium catalysts can be recovered and recycled.
(b)
Interpretation:
The substituted alkene that is used in the Heck reaction to make the given products is to be stated.
