[caanmaro]

Hello friends

As can be explained by a logic synthesis mechanism of the following compound enclosed by styrene

[Altered State]

As I told you in the other post, you need to show that you have attempted to solve the problem.

I want to know whether this mechanism is correct and if you can design another

Thanks friends

Drawing hydrogen as part of a 3-membered ring is unusual, and it implies that hydrogen can have four electrons, which is not correct.

Caanmaro's representation that depicts "hydrogen as part of a 3-membered ring" might be considered to be the equivalent of a pi-complex, i. e., a transient species that results from an initial Lewis acid - Lewis base interaction between C=C and H+.

The resulting pi-complex most likely is kinetically unimportant; it immediately reorganizes itself into a sigma-bonded carbocation intermediate as shown in Step 2 of the mechanism depicted in Reply #2.

Thus, it's possible that Caanmaro's representation simply may reflect limitations imposed by the simplified molecular-input line-entry system (SMILES).

With regard to the mechanism shown in Reply #2: Please reconsider the structure of the carbocation intermediate formed in Step 4 (i. e., that which leads to the final reaction product via Step 5).
