The following question was sent to me . The answer for this question was given to me as option b
In order to get option B , I have to assume ylide generating a carbene and this may insert to double bond.
I have not come across phosphorous ylide as carbene generating reagent.
My question is as follows:
Will phosphorous Ylide participate in carbene generation and insertion in the presence of double bond ?
An answer in this regard would be quite help full.
