Tris(2-pyrdiylmethyl)amine was purchased from TCI America. Brij 30, Brij 35, copper (II)bromide (991 %), acetone-d6 (99.8% D), and deuterium oxide (99.8% D) were purchased from Acros Organics. Tris(hydroxypropyl)phosphine (THP) and tris(2-carboxylethyl) phosphine (TCEP) were purchased from EMD Millipore. Tetrahydrofuran, acetone, hydrochloric acid, hexanes, and methylene chloride were purchased from Fisher Scientific. Poly(ethylene glycol) monomethyl ether monomethacrylate, M_n 1000 (PEGMA1k) was purchased from Polysciences. All chemical were used as received. For reactions in D₂O, PEGMA2k was prepared as described in the literature.³¹
