Step-by-step solution

Grubbs catalyst

Grubbs catalysts form a primary part of synthetic organic chemistry. These catalysts are carbene complexes consisting of transition metals and are utilized in olefin metathesis.

Reaction of alkene with Grubbs catalyst

Alkenes combine with Grubbs catalyst to generate several products, and this process is termed olefin metathesis. Two or several alkenes are obtained as products in this particular reaction.

Products formed on the reaction of each alkene with the Grubbs catalyst

a. The reaction of the given alkene with Grubbs catalyst results in the formation of E and Z isomers. The reaction of compound a with Grubbs catalyst can be given as:

Reaction of compound a with Grubbs catalyst

b. The reaction of the aromatic alkene with Grubbs catalyst leads to the generation of E and Z isomers of the alkene. The reaction can be given as:

Reaction of compound b with Grubbs catalyst

c. The reaction of the given compound with Grubbs catalyst leads to the formation of Z isomer. The reaction of compound c with Grubbs catalyst can be given as:
