Halide-Rebound Polymerization of Twisted Amides.
J. Am. Chem. Soc. 2019;
141: 2906-2910
Key words
twisted amides - chain-growth polymerization - living polymerization
Significance
The development of new methods for chain-growth polymerization enables the investigation
of novel monomer and polymer architectures with precise control over molecular weight.
In this study, Gutekunst et al. develop the Halide-Rebound Polymerization (HaRP),
which takes advantage of the increased nucleophilicity of twisted amide 1.
Comment
By using an alkyl iodide as an initiator, the resulting chain end is neither air-
and moisture-sensitive. This enables the facile synthesis of block co-polymers, as
well as quantitative end-group functionalization. Polymer structure was confirmed
by both model studies and MALDI-ToF analysis.
