## Abstract Synthetic routes to twenty‐six new crown ether compounds with pendent amine, amide, __O__‐benzylhydrox‐amate, and urethane groups are reported. The new lariat ether compounds are based on __sym__‐dibenzo‐16‐crown‐5, __sym__‐dicyclohexano‐16‐crown‐5, and 14‐crown‐4 scaffolds.
Linear polyaryl(ether ketones) containing tert-butyl pendent groups were prepared from aromatic hydrocarbons and aromatic diacid chlorides, both classes of monomers containing tert-butyl pendent groups. The polymers were prepared in high yield and high molecular weight by low-temperature precipitati
## Abstract A series of structurally related dibenzo‐15‐crown‐5, dibenzo‐18‐crown‐6, and dibenzo‐21‐crown‐7 compounds with oxymethylacetoxy side arms is synthesized by reaction of the corresponding crown ether alcohols with potassium hydride and bromoacetic acid. Multi‐step synthetic routes to the
