2.3.1. Syntheses of ligands
General procedure: L1-L3 were prepared by a standard method reported in theliterature [19]. The preparations are shown in Scheme 1.L1: 1H,3H-benzo[1,2-c:4,5-c0]difuran-1,3,5,7-tetraone (4.36 g,0.02 mol) and 3-aminopropanoic acid (3.56 g, 0.04 mol) wereadded into a three-neck flask with 40 mL DMF in it. The reactionmixture was stirred for 8 h in an oil-bath at 90 C. After standovernight, the mixture was filtrated to get the pale yellow powder.After washed with ethanol till the filter liquor turned colorless, thepowder which turned whitewas recrystallized in a small portion ofDMF. Yield: 87.3%; Mp: > 300 C. |

Stage #1: triphenyltin(IV) hydroxide; 2,2'-(1,3,5,7-tetraoxo-5,7-dihydropyrrolo[3,4-f]isoindole-2,6(1H,3H)-diyl)dibenzoic acid In toluene Dean-Stark; Reflux;
Stage #2: ethanol |
2.3.4. Synthesis of [(Ph3Sn)(CH3CH2O)]2(L3) (3)
General procedure: A mixture of triphenyltin hydroxide (0.367 g, 1 mmol) and L1(0.180 g, 0.5 mmol) was heated under reflux in toluene (50 ml) for10 h in a Dean-Stark apparatus for azeotropic removal of the waterformed in the reaction. After cooling to room temperature, thesolution was filtered. The filtrate was gradually evaporated and theX-ray quality colorless crystals were obtained. |
