from Thermo Fisher Scientific and purified using a basic alumina column
to remove inhibitor. Tetrahydrofuran (THF), anisole, toluene, acetone,
and isopropanol were purchased from Fisher Scientific and used as

(MCR-M17, Mn = 5000 g/mol, DP = 70, Đ = 1.15) was obtained from Gelest and purified using
basic alumina columns to remove inhibitor. Copper(I) bromide (CuBr,
99.999%), tris[2-(dimethylamino)ethyl]amine (Me6TREN),
and ethylene bis(2-bromoisobutyrate) (2-BiB, 97%) were purchased from
Sigma-Aldrich and used as received.
