“…Derivatives (9)(10)(11) In a manner similar to the synthesis of 8, 4-trimethylstannyltetrathiafulvalene derivatives 9, 10, and 11 were prepared from 4,5-bis(methylthio)tetrathiafulvalene (BMT-TTF), 4,5-ethylenedithiotetrathiafulvalene (EDT-TTF), and 4,5-ethylenedioxytetrathiafulvalene (EDO-TTF) in 48%, 55%, and 29% yields, respectively. 9: orange oil, 1 In a manner similar to the synthesis of 2 with Pd(OAc) 2 , bi-TTFs (1, 3, and 4) were synthesized by the reaction of the corresponding trimethyltin-TTF derivatives (8, 10, and 11) with Pd(OAc) 2 To a solution of TTF (207 mg, 1.01 mmol) in THF (5 mL) was added dropwise over 7 min a hexane solution of n-BuLi (1.53 M, 0.7 mL, 1.07 mmol) at -781C under argon atmosphere, and the mixture was stirred at the same temperature for 1 h. A solution of zinc chloride (163 mg, 1.20 mmol) in THF (3 ml) was added dropwise at -781C, and the mixture was stirred at the same temperature for 1 h. The mixture was allowed to warm to À101C, and then PdCl 2 (PPh 3 ) 2 (352 mg, 0.501 mmol) was added to the mixture.…”
