Ok, I'm wondering if this reaction is possible (it seems like it should be but I have not been able to find any examples, or any examples of the product actually existing)


I attached a sketch of this potential reaction. Does this reaction actually occur via SN2? I only drew the organic products, and I haven't shown stereochemistry - but I'd really love a simple answer from someone with experience.

It seems that this should occur, but I am unsure.

I'd really appreciate any help possible. Also, I don't believe there are any other possible products, but if I have written this reaction wrong, please let me know.


Thanks in advance

It's not a SN2 reaction because there isn't inversion of the stereochemistry.  It's more like an SN1 reaction with retention of stereochemistry.  The rationale for the retention of stereochem is a non-classical carbocation intermediate.

Anchimeric assitance of the double bond  is likely to influence this reaction solely if the product you have shown is formed exclusively.

please view the following URL for more info:

what I think: In this reaction anchimeric assistance is not possible or is lessened due to the existance of an electron withdrawing group being attached to the double bond , hence the reaction should produce more than one product .

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex
