We have prepared new organic anionic acceptors Br(2)XQNHCH(2)SO(3)(-) (2 X=Br 3 X=BryCl1-y (y approximate to 0 5) 4 X=Cl Q=1 4-benzoquinone) that possess both an electron acceptor part (1 4-benzoquinone) and an anionic part (sulfonate) The reduction potentials of the PPh4 salts of 2 3 and 4 are -0 45 -0 45 and 0 46 V (vs SCE in CH3CN) respectively The results indicate that they are weaker acceptors than chloranil (-0 13 V) and bromanil (-0 12 V) Each anionic acceptor (AA) provided two BEDT-TTF salts be
