Abstract A simple new method has been devised for the preparation of α- isothiocyanatoethers 1a-1f in good yields by reaction of PO (NCS) 3 or (PhO) 2 PONCS with an equimolar mixture of aldehydes and alcohols. The course of nucleophilic additions of methanol, amines and hydrazine to 1a-1f is described.
