Facile preparation of optically active helical polycarbenes with salicylate substituents and their postpolymerization modification

Optically active helical polycarbenes were constructed through the living and controlled helix-sense-selective polymerization (HSSP) of methyl salicylate modified diazoacetate monomer catalysed via pi-allylPdCl with chiral phosphine ligands. The obtained helical polycarbenes could undergo postpolymerization modification to afford functional polycarbenes efficiently.

Automated summary

Optically active helical polycarbenes were synthesized by catalyzing the living and controlled helix-sense-selective polymerization (HSSP) of methyl salicylate modified diazoacetate monomer with pi-allylPdCl using chiral phosphine ligands. The resulting helical polycarbenes could be postpolymerization modified to produce functional polycarbenes efficiently.
