  • Synthetic Procedure: See article for the definitive version of this procedure and for full experimental details.6 (19.0 mg, 14.7 µmol), CuI (3.4 mg, 17.7 µmol), Pd2dba3(4.0 mg, 4.4 µmol), and tri(t‑butyl)phosphine (6.0 mg, 29.5 µmol) were mixed in a microwave tube and sealed with a septum. In parallel, a solution of 5 (241.7 mg, 132.6 µmol) in piperidine (2 mL) was purged with argon for 1 h. Then the latter was transferred to the microwave tube and the mixture was heated at 120 °C for 16 min in a microwave instrument (max. power: 300 W). After cooling to r.t., the tube was opened and the reaction mixture was diluted with MTBE. The organic phase was washed with aq. H2SO4 (10 %) and brine. It was dried over MgSO4 and the solvent was removed under reduced pressure. The residue was purified by column chromatography (CH:DCM = 65:35 ‑ 68:32), and 7 (126 mg, 10.9 µmol, 74 %) was obtained as a yellow solid. 1H NMR (500 MHz, CDCl3, 298 K) δ [ppm] = 8.09 (d, 3JH,H = 8.2 Hz, 12 H), 7.87 (d, 3JH,H = 8.5 Hz, 12 H), 7.76 – 7.60 (m, 48 H), 7.55 – 7.46 (m, 12 H), 7.16 (d, 3JH,H = 8.0 Hz, 12 H), 7.03 (s, 6 H), 7.02 (s, 6 H), 6.96 (s, 12 H), 6.93 (s, 12 H), 6.86 (d, 3JH,H = 8.1 Hz, 12 H), 4.10 – 3.99 (m, 48 H), 3.99 – 3.90 (m, 24 H), 2.42 (t, 3JH,H = 7.0 Hz, 24 H), 1.95 – 1.72 (m, 96 H), 1.62 – 1.16 (m, 360 H), 1.15 – 0.97 (m, 168 H), 0.97 – 0.76 (m, 132 H); 1H NMR (500 MHz, CD2Cl2, 298 K) δ [ppm] = 8.14 (d, 3JH,H = 8.1 Hz, 12 H), 7.92 (d, 3JH,H = 8.5 Hz, 12 H), 7.79 – 7.66 (m, 36 H), 7.64 (s, 12 H), 7.54 – 7.44 (m, 12 H), 7.20 (d, 3JH,H = 8.2 Hz, 12 H), 7.05 (s, 6 H), 7.02 (s, 6 H), 6.99 (s, 12 H), 6.97 – 6.93 (m, 24 H), 4.08 – 3.98 (m, 48 H), 3.98 – 3.92 (m, 24 H), 2.41 (t, 3JH,H = 7.0 Hz, 24 H), 1.96 – 1.71 (m, 96 H), 1.65 – 1.17 (m, 360 H), 1.17 – 0.99 (m, 168 H), 0.99 – 0.76 (m, 132 H); 13C NMR (126 MHz, CDCl3, 298 K) δ [ppm] = 154.78, 154.06, 153.94, 153.79, 141.60, 140.49, 140.41, 140.10, 136.79, 132.63, 131.73, 130.90, 128.94, 127.99, 127.36, 124.58, 123.55, 123.50, 121.54, 121.26, 120.86, 120.21, 118.04, 117.40, 117.28, 116.51, 114.96, 114.65, 114.07, 113.58, 113.47, 104.31, 96.51, 95.56, 94.91, 87.61, 86.62, 70.16, 70.04, 70.00, 69.56, 32.27, 32.25, 32.24, 32.18, 29.82, 29.79, 29.75, 29.73, 29.71, 29.68, 26.52, 26.42, 26.40, 23.14, 23.13, 23.09, 23.08, 21.70, 21.17, 18.65, 18.41, 14.63, 14.57, 14.52, 14.50, 12.20, 10.04; 13C NMR (126 MHz, CD2Cl2, 298 K) δ [ppm] = 154.88, 154.20, 154.11, 153.93, 141.87, 140.89, 140.63, 140.50, 140.40, 136.88, 132.68, 132.04, 130.83, 129.11, 128.15, 127.61, 124.49, 123.69, 123.50, 121.66, 121.44, 121.10, 120.32, 117.99, 117.47, 117.28, 116.70, 114.90, 114.62, 114.20, 113.84, 113.62, 104.31, 96.45, 95.91, 95.35, 94.94, 87.71, 86.85, 86.80, 70.22, 70.14, 69.82, 32.44, 32.35, 29.97, 29.93, 29.90, 29.88, 29.83, 29.83, 26.69, 26.67, 26.58, 26.54, 23.31, 23.29, 23.25, 23.24, 21.89, 21.22, 18.56, 18.32, 14.57, 14.50, 14.45, 14.43, 12.35, 10.14;MS (MALDI-TOF, DCTB) (calcd. for C774H996N18O36Si12 monoisotopic: 11455.39, distr. max.: 11465.32): m/z11965.9 [M+2*DCTB]+, 11716.6 [M+DCTB]+, 11465.3 [M]+, 5856.8 [M+DCTB]2+, 5733.5 [M]2+; GPC (in THF vs. PS): Mp = 11580 g mol-1.
