The great potential of subphthalocyanines (SubPcs) to stabilize boron peroxides has been demonstrated. In particular, a subphthalocyanato boron (III) peroxide has been prepared in good yield via boron triflate. This derivative is remarkably stable under ambient conditions and can be fully characterized. The impact of the peroxide group on the structural and optoelectronic properties of SubPc was examined by NMR and UV/Vis spectroscopies, as well as single-crystal X-ray diffraction analysis. Moreover, density functional theory calculations were performed to explain the experimental results. The reactivity of this peculiar boron peroxide as an oxidant and a Lewis base was also studied.

  • 12 Synthetic procedure for t BuOO-SubPcH12: In a 10 mL round-bottomed flask, equipped with a magnetic stirrer and a rubber seal, Cl-SubPcH12 (0.025 mmol) and silver trifluoromethanesulfonate (0.031 mmol; 1.25 equiv) were placed. Anhydrous toluene (3 mL) was added and the mixture was stirred under an argon atmosphere at room temperature until the disappearance of the SubPcCl starting material, which was monitored by TLC. At this point tert-butyl peroxide (5–6 M in decane, 0.031 mmol, 1.25 equiv) and N,N-diisopropylethylamine (0.031 mmol, 1.25 equiv) were added. The reaction mixture was then stirred at 50 °C for 20 min. The residue was purified by column chromatography on silica gel using toluene/AcOEt (5:1) as the eluent. The product obtained from the column was further purified washing with cold hexane. t BuOO-SubPcH12 was isolated as a pink solid in 86%. 1H-NMR (300 MHz, CDCl3): δ ppm = 8.88 (m, 6 H), 7.89 (m, 6 H), 0.34 (s, 9 H). 13C-NMR (75.5 MHz, CDCl3): δ ppm = 151.6, 131.2, 129.8, 122.3, 25.4. 11B-NMR (96 MHz, CDCl3): δ ppm = −13.8. HRLSI-MS (MALDI-TOF): Calculated for C28H21BN6O2: 484.1819; Found: 484.1840. UV/vis (DCM): λmax (nm) (log ε); ΦF (exc. λ = 570 nm) = 0.86; FT-IR: ν (cm −1) = 3062, 2972, 2913, 1613, 1453, 1283, 1128, 1058, 744. Mp > 200 °C
