Ketene dimerization is the best known example of such a cycloaddition. (image source) As you add substituents to the ketene $\ce{C=C}$ double bond, you begin to favor cycloadditon across the carbon-carbon double bond at the expense of cycloaddition across the carbonyl double bond. Oct 15, · This chapter is a review of cycloaddition reactions of ketenes. Here, a cycloaddition is defined as a reaction of a ketene with an unsaturated organic compound to give a cyclic product by a mechanism that, in principle, involves the almost simultaneous formation of .

Certainly. And I have faced it. Let's discuss this question. Here or in PM.
In it something is also idea good, agree with you.
