Abstract: A new type of quaternary ammonium compounds is reported. It is found to posses ahigher phase transfer catalytic behavior than the commonly used quaternaty ammoniumcompounds and dibenzo-18-crown-6 for dichlorocarbene formation.

Key words: phase transfer catalyst, quaternary ammonium compound, dich lorocarbene, cyclohexene, benzylalehyde
