3-Ethyl-6-vinyltetrahydro-2H-pyran-2-one (EVP): a versatile CO₂-derived lactone platform for polymer synthesis

Abstract

3-ethyl-6-vinyltetrahydro-2H-pyran-2-one (EVP) is a CO2-derived lactone synthesized via Pd-catalyzed telomerization of butadiene. As EVP is 28.9% by weight CO2 it has received significant recent attention as an intermediary for the...

A Topology‐Defined Polyester Elastomer from CO2 and 1,3‐Butadiene: A One‐Pot‐One‐Step “Scrambling Polymerizations” Strategy

“…[21] Very recently, the anionic ROP of EtVP and HL, the hydrogenated EVL derivatives, reveals the reactivity of unconjugated di-substituted six-membered lactone ring. [22][23][24][25] Herein, a novel strategy named "scrambling polymerizations" is designed to produce non-cytotoxic and degradable polyester elastomer using EVL and ɛ-caprolactone (CL) by one-pot-one-step copolymerization (Scheme 1). The topology of obtained polyester is tunable to be cyclic, branched and crosslinked.…”

A Topology‐Defined Polyester Elastomer from CO2 and 1,3‐Butadiene: A One‐Pot‐One‐Step “Scrambling Polymerizations” Strategy

“…Cationic ring‐opening copolymerization suffers uncontrollable transfer [21] . Very recently, the anionic ROP of EtVP and HL, the hydrogenated EVL derivatives, reveals the reactivity of unconjugated di‐substituted six‐membered lactone ring [22–25] . Herein, a novel strategy named “scrambling polymerizations” is designed to produce non‐cytotoxic and degradable polyester elastomer using EVL and ϵ‐caprolactone (CL) by one‐pot‐one‐step copolymerization (Scheme 1).…”

Sourcing, thermodynamics, and ring-opening (co)polymerization of substituted δ-lactones: a review

“…[71][72][73] Moreover, the 2 alkene groups could be hydrogenated to give one alkene and one ethyl (EtVP) or a diethyl (DEP) lactone. 74,75 The first one could also be obtained through selectively reducing EVP using triethoxysilane and Stryker's reagent ([(Ph 3 P)CuH] 6 ). 76 The last interesting functionalized lactone is propargyl functionalized δ-VL (α-propargyl-δ-VL, αPδVL).…”
