A question in Murray text book --p.p524 /Q 15.30
3-chlorocyclopentene , on treatment with AgBF4 , gives a precipitate of AgCl and a stable solution of a product that shows a single 1HNMR absorption at 11.04 chemical shift.
-What is it likely structure of the product ?
-What is its relation to Huckel rule ?
I go and search for chemical shift , the 11.04 accounted for a carboxylic acid functional group
And since it is single signal, it may due to the exchange of OH disrupt coupling.
However, i cant come out with the likely structure, because in the reaction there is nothing seems can form an -OH group. I know about Huckel rule but i cant explain before i can work out the structure
Does anyone has any idea what happens when we add AgBF4 to 3-chlorocyclopropene ?
