| Popis: |
In the microwave-assisted alcoholysis of dialkyl phenylphosphonates performed in the presence of suitable ionic liquids, such as [bmim][BF4] or [bmim][PF6], affording the phosphonate with mixed alkoxy groups and the fully transesterified product, the fission of the phosphonate function to the ester-acid or diacid moiety was inevitable. Moreover, in the presence of [emim][HSO4], the reaction could be performed to afford the phosphonic esteracid with a selectivity of 66% and the diacid with a selectivity of 97%. The ester-acids provided by the new protocol may be valuable intermediates. |
