Abstract

Preparation of 1-10 carbon alkyl, 3-10 C alkenyl or aryl-(1-4 C)-alkyl cyanoacetates comprises reacting an alkali cyanoacetate with an alk(en)yl or arylalkyl halide (II) in an aqueous-organic 2-phase system in the presence of a phase transfer catalyst. Preparation of 1-10 carbon (C) alkyl, 3-10 C alkenyl or aryl-(1-4 C)-alkyl cyanoacetates of formula (I) comprises reacting an alkali cyanoacetate with an alk(en)yl or arylalkyl halide of formula RX (II) in an aqueous-organic 2-phase system in the presence of a phase transfer catalyst. R = 1-10 C alkyl, 3-10 C alkenyl or aryl-(1-4 C)-alkyl; X = chlorine (Cl), bromine (Br) or iodine.
