1,1-disubstituted ethylene process
Process for the production of methylidene malonates and cyanoacrylates employing in-situ formed iminium salts derived from acid halides and/or acid anhydrides and N,N,N′,N′-tetra hydrocarbyl diaminoalkanes, the acid halides and/or acid anhydrides being present in a molar excess relative to the diami...
