Using 2-iodo-2,3-dihydro-2,2'-bithiophene, tetraethyl (5,5'-bis(tributylstannyl)-[2,2'-bithiophene]-3,3'-diyl)bis(phosphonate) to produce tetraethyl [2,2':5',2'':5'',2''':5''',2'''':5'''',2'''''-sexithiophene]-3''',4''-diylbis(phosphonate), please predict the condition, including solvent and agent in SMILES notation in json format like:

```JSON
{
    "solvent": [
        "CCN(CC)CC",
        "CCOC(C)=O"
    ],
    "agent": [
        "On1nnc2ccccc21",
        "C(=NC1CCCCC1)=NC1CCCCC1",
        "Cl"
    ]
}
