I am trying to prepare the aforementioned adduct and reacting with a substituted benzyl alcohol to get the acrylate monomer following the publication Prof. Jonathan M. J. Williams and Co-Workers:

ChemInform 01/2003; 44(29):5523-5525. DOI: 10.1016/S0040-4039(03)01272-3

However unexplained and unrepeated results are obtained, though it is mentioned in this paper that the reaction is straightforward.
