New substituted N-phenyl-3-phenylaminoacrylimidate zinc complexes useful as catalysts, especially for polycarbonate production by reaction of epoxides with carbon dioxide

摘要

Substituted N-phenyl-3-phenylaminoacrylimidate zinc complexes (I) are new. Substituted N-phenyl-3-phenylaminoacrylimidate zinc complexes of formula (I) are new: R1, R2, R7, R8halo or alkyl; R3H or optionally substituted alkyl or aryl; R4CN, H, COOR6, CF3, NO2 or aryl; R5optionally substituted alkyl, aryl, allyl, heterocyclyl, alkaryl or alkyl-heterocyclyl; R6alkyl or aryl; X : OR, RCOO or RSO2; R : alkyl or aryl.
