Unless noted otherwise, reactions were conducted under dry N2 and monitored via 1H NMR spectroscopy until conversions were >90%. [1]0 = initial concentration of 1; [C]0 = initial catalyst concentration
Molecular weight data obtained via GPC with multiangle laser light scattering.
Maximum conversion = 60%.
Maximum conversion = 39%
