Reactions were conducted under Ar atmosphere at 50 °C using [2/4]₀ or [3/4]₀ = 40:1 and [2/5]₀ or [3/5]₀ = 2.5:1.

Isolated yield after precipitation, based on 2 or 3 accordingly.

Determined by ¹H NMR spectroscopy of the isolated product.

Determined by gel-permeation chromatography using multi-angle laser light scattering.

Using [2b/DB24C8]₀ = 1:1.

Using [2b/DB24C8]₀ = 5:1.
