Question

Question: Which of the following compounds can serve as Michael acceptors?

Step-by-Step Solution

Answer

Answer

 

1. Yes
2. No
3. No
4. Yes

Step 1: Michael acceptor

A Michael acceptor is the $\mathit{\alpha }\mathbf{,}\mathit{\beta }$ unsaturated carbonyl compound. The general structure is shown below:

$\alpha ,\beta -$ unsaturated carbonyl compound

Step 2: Explanation

a.

 

The given compound is $\alpha ,\beta$-unsaturated. Thus, it is a Michael acceptor.

 

b.

 

The given compound is not $\alpha ,\beta$-unsaturated. Thus, it is not a Michael acceptor.

 

c.

 

The given compound is not $\alpha ,\beta$-unsaturated. Thus, it is not a Michael acceptor.

 

d.

 

The given compound is $\alpha ,\beta$-unsaturated. Thus, it is a Michael acceptor.
