Abstract

Silver-fausajite type zeolites 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.
