The perimeter reaction machine
The perimeter reaction (also known as the electro-ring reaction) is an organic chemical reaction involving
The formation of polycyclic compounds. Peripheral reaction mechanisms may be affected by the type of reaction and the underside
In contrast, the following is a common overview of the logic of the circular response。
1.
Cyclical response: the circular reaction usually involves double keys in organic molecules
Three or other active groups. These active cells can be used through neamide, rings. Internal
Reactions such as alcohol or cyclodone generate stable rings. Could be involved in creating rings
And steps such as proton transfers, pro-nuclear attacks or electronic transfers。
2.
Selective conditions: selectiveness of the surrounding response is important and can be achieved through choice
Appropriate substrates and reaction conditions to control the formation of products. For example, the choice is right
Solvents, temperature and catalysts, etc., can be tailored to control response pathways
And product selection。
3.
Response intermediate: the peri-reaction usually involves the formation and transformation of the intermediate. Here
Some of the intermediates can be temporary products of inter-ring reactions or stable. Medium
Istituto, as a further transformation species。
I'm sorry.
Convergence: the existence of conglomerate systems is very common in the conjunctive response because
These systems have a lower responsiveness and higher stability. Convergence structure
It can be formed by electronic co-mingling, mosaicing orbits, etc., to facilitate a peripheral reaction
Let's go。
It's important to note that the rectangular reaction can be very complex and usually requires examination
Consider multistep reactions and possible by-products. Therefore, a specific rectangular response mechanism is possible
Multiple intermediates and response steps involved, to be carried out through experimental and theoretical research detail
