were able to catalyse, without solvents and at low silver loading, the formation of (spiro)ketals from alkyn(edi)ols. Such Ag-zeolite catalysts could be recycled without any activity loss. This study constitutes the first (spiro)ketalization mediated by silver heterogeneous catalysts, but also a truly ‘green’ (spiro)ketalization.
银福山石型 沸石 能够催化,而无需 溶剂在低银含量下,由炔(乙二胺)醇形成(螺)缩酮。这种银沸石催化剂可以回收利用而不会损失任何活动。这项研究构成了银异质介导的第一个(螺)缩酮化反应催化剂,而且是真正的“绿色”(螺旋)缩酮化。
