ABSTRACT:
1,1-disubstituted ethylene compounds of the general formula I ##STR1## where Z is COOR.sup.2, CN or COR.sup.3, R.sup.1 is an aliphatic, cycloalophatic, araliphatic, aromatic or heterocyclic radical which may be further substituted by functional groups which are inert under the reaction conditions, R.sup.2 is an aliphatic, cycloaliphatic or araliphatic radical of 1 to 15 carbon atoms and R.sup.3 is an aliphatic, cycloaliphatic or araliphatic radical of 1 to 15 carbon atoms which may be substituted by groups which are inert under the reaction conditions, and R.sup.1 together with R.sup.2 or R.sup.1 together with R.sup.3 may furthermore form an alkylene chain of 2 to 10 carbon atoms which may be substituted by groups which are inert under the reaction conditions, are prepared from a formyl compound of the general formula II ##STR2## where Z, R.sup.1, R.sup.2 and R.sup.3 have the above meanings, by a process in which the reaction is carried out in the presence of formaldehyde or paraformaldehyde and
