Preparation of Polyenaryloxynitriles from Dicyanovinyl Chloride and Diphenol Derivatives in the Presence of DABCO
Neri Geum, Myoung-Seon Gong
The kinetic study of the enaryloxynitriles via the nucleophilic vinylic substitution reaction of various phenol derivatives with 1-chloro-1-phenyl-2,2-dicyanoethene (1) was conducted in the presence of 1,4-diazabicyclo[2,2,2]octane (DABCO). Nucleophilic vinylic substitution of phenol derivatives with electrophilic olefins carrying sluggish leaving group involves a third-order reaction. The reaction was applied to solution polymerization of diphenol derivatives with p-bis(1-chrolo-2,2-dicyanovinyl)benzene (2), which yielded various polyenaryloxynitriles with moderate molecular weight.
