i am making areaction with (-)Menthyl (R)-p-toluenesulfinate with methylmagnesium iodide, the reaction thake place at anhydrous benzene. after doing the reaction i am making hydrolyse with ammonium chloride.
so i have to question about the reaction:
A. why does my solvent is benzene? why not to do it in anhydrous ether?
B. why do i make hydrolise with ammonium chloride? which reaction is accure? what is the mechnism? why not to hydrolise with water?
