There are a number of synthetic pathways to NVF monomer, however, all of the commercially attractive routes require the elimination of HX from the precursors CH3CH(X)NHCHO where X = CN, OR, NHCHO. The technology leading to CH3CH(X)NHCHO requires as the first step condensation of acetaldehyde with HX where X = CN or NHCHO.
