A probe into the 1. 3-Dipolar Cycloaddtion and Its Reaction Mechanism
Shen Jianxin (Department of Chemistry)
This paper introduce 1, 3-dipolar cycloaddition as a type of reaction, and also mentioned several disputed mechanisms and arguments: R.Hiusggen's concerted mechanisms R.A.Firestone's a two-step mechanism with diradical intermediate and so on,in which the fomer has been widely accepted.The core of the concerted mechanism reaction is synchronization. Because absolute synchronism is nonexistent, therefore the concerted reaction will involve some latant unconcertdness.
