The ROR′-DADQs were synthesized by the direct addition of the alkoxyalkylamine (3.92 mmol) to a warm solution of TCNQ (200 mg, 0.98 mmol) in 20 mL acetonitrile (caution: HCN is a by-product in this reaction). The solution was stirred at 70 °C f or 3 h; it was then brought to the ambient temperature and subsequently cooled at -7 °C f or 24 h. The precipitate obtained was f iltered and dried (yield ∼ 80%). It was purif ied by multiple recrystallizations f rom methanol or acetonitrile and characterized. Slow evaporation of these solutions yielded block or plate-type single crystals.
