Reacts with 1,2-diols, e.g. sugars, to form 1-(dimethylamino)ethylidene cyclic acetals which can be cleaved with aqueous AcOH, giving the monoacetate of the less hindered OH, thus providing a method for selective monoprotection of the diol: Can. J. Chem., 50, 233 (1972).

Reacts with active methylene compounds to give the (dimethylamino)ethylidene derivatives: Liebigs Ann. Chem., 641, 1 (1961), compare N,N-Dimethyl­formamide dimethyl­ acetal, A15350.
