Synthesis and properties of novel poly(aryl ether ketone)s containing imide linkages in the main chains A new monomer containing imide linkages, bis[4-( p -phenoxybenzoyl)-1,2-benzenedioyl]- N , N , N ′, N ′-4,4′-diaminodiphenyl ether (BPBDADPE), was prepa... Z Hong,Q Xi,...
The new N-(arylsilyl)anilines 1–5 have been obtained by the reaction of aryl(halo)silanes with the corresponding anilines in the presence of the auxiliary base triethylamine. The benzene parts of the anilines have been chosen such that their fluoro, methyl, and methoxy substituents exert dif...
