Abstract The opening of A-dicyanoepoxides by pyridine polyhdrofluoride yields polymerisable 2-fluorocyanoformyls which may be kept intact when diluated in dichloromethane or ether. These intermediates react with nuclecophiles such as water, methanol or amines to give respectivly 2-fluoroacids, esters or amides.

The present paper describes the enantioface-differentiaing epoxidation of alkylidenemalononitriles with molecular oxygen, catalyzed by chiral tertiary amines. In the light of the by-product formation, the reaction path was concluded to involve intermolecular nucleophilic attack of a hydroperoxide intermediate catalyzed by a chiral tertiary amine. A similar epoxidation was demonstrated with cumylhydroperoxide in the presence of nicotine.
