Participants

Reaction Steps

To a suspension of 1,2,3,4,8,12,13,14,15,19-deca(4′-t-butylphenylthio)nonacene-6,10,17,21-tetraone (0.5 g, 0.23 mmol) in dry THF (10 mL) under a N2 atmosphere was slowly added NaBH4 (0.1 g, 2.64 mmol). The reaction mixture was stirred at room temp for 3 h, and then quenched with H2O. The resulting mixture was filtered, washed with H2O, and dried in vacuo to give the desired product as a light yellow solid (0.47 g, 94%). LDI-MS m/z: 2188 [M+], 2171 [M+-OH]. The laser desorption ionization mass spectrum (LDI-MS) of 1,2,3,4,8,12,13,14,15,19-deca(4′-t-butylphenylthio)-6,10,17,21-tetrahydrononacene-6,10,17,21-tetraol is shown in FIG. 14B. The compound structure is shown in FIG. 14A.
