Synthesis of Single-stranded Polynorbornene with Pendant Group Bearing Benzenedicarboxaldehyde and Long Alkyl Chain

摘要

An unprecedented single-stranded polynorbornene with the pendant group containing benzenedicarboxaldehyde and a long alkyl chain(12) was synthesized by ring-open metathesis polymerization(ROMP) of the corresponding monomer(11),which was obtained via the esterification of two crucial intermediates,namely,2-hexadecyloxy-5-hydroxymethyl-1,3-benzenedicarboxaldehyde(7,obtained via 6 steps) and 4-(4-aza-tricyclo[5.2.1.0 2.6 ]-dec-8en-4-yl)benzoic acid(10).The target compound and all the intermediates were characterized by infrared(IR),1 H NMR and high resolution mass spectroscopy(HRMS) analysis.
