The complex [TlR3(diox)](diox = 1,4-dioxan) has been prepared by the reaction of TlCl3 with LiR (R = 2,4,6-C6F3H2), or of [NBu4][TlR4] with HBF4(R = C6F5) and subsequent addition of dioxan. The displacement of dioxan by (a) neutral ligands leads to [TlR3L](L = OPPh3, pyridine, PPh3, or Ph2PCH2PPh2); (b) anionic ligands affords Q[TlR3X]Q =[NBu4]+ or [N(PPh3)2]+; X = Cl–, CN–, NO3–, or CF3CO2–}; and
通过TlCl 3与LiR(R = 2,4,6-C 6 F 3 H 2)或[NBu]的反应制备了配合物[TlR 3(diox)](diox = 1,4-二恶烷)4 ] [TlR 4 ]和HBF 4(R = C 6 F 5),然后加入二恶烷。(a)中性配体取代二恶烷导致[TlR 3 L](L = OPPh 3,吡啶,PPh 3或Ph 2 PCH 2 PPh 2);(b)阴离子配体提供Q [TlR 3 X] Q = [NBu4 ] +或[N(PPh 3) 2 ] +;X =氯-,CN -,NO 3 -,或CF 3 CO 2 - }; ( c)羰基金属盐得到Q [TlR 3 M *] M * = [Mo(cp)(CO) 3 ] –(cp = η–C 5 H 5),[W(cp)(CO) 3 ] –,[Co(CO) 4 ] –或[Mn(CO) 5 ] – }。
