“…Spandau and Brunneck (504) found that (C2Hs)4NCl potentiometrically titrated against SbCls in thionyl chloride only gave evidence for a 1:1 complex, but pyridine (and some other nitrogen bases) gave inflections at Py/SbCls mole ratios of 1:1, 2:1, 3:1 ?, and 4:1. Such titration experiments have been carried out in POCl3 (22,189,190,192,194,207, 210, 211); S02C12 (193); SOCl2 (192,504); AsCl3 (9,187,188,191,192); IC1 (183,186,188); S02 (253); BrF3 (557); C6H6C0C1 (213); CeHsPOCl, (30, 31); CHgCC^Hs (421).…”
