Chapter 26: Q 29. (page 1070)

What ring-closing metathesis product is formed when each substrate is treated with Grubbs catalyst under high-dilution conditions?

a.

b.

c.

Short Answer

Expert verified

Answer

Product of b

Step by step solution

01

Ring-closing metathesis

Under the reactions of olefinic metathesis, the intramolecular metathesis of the terminal alkenes that form multiple unsaturated rings is called ring-forming metathesis. The cycloalkenes formed are E and Z isomers.

02

Grubbs catalyst

The series of the transition metal carbenes used especially for olefinic metathesis are the Grubbs catalysts.

03

Products of the given reaction

Under high-dilution conditions, the Grubbs catalyst favors the intramolecular ring-closing metathesis.

a. A six-membered ring is formed by the intramolecular metathesis. The product is shown below.


Product of a

b. A six-membered ring is formed by the intramolecular metathesis. The product is shown below.

Product of b

c. A five-membered ring is formed by the intramolecular metathesis. The product is shown below.

Product of c
