= C6(NO2)2-2,6-(OMe)3-3,4,5-C1 (2)), obtained by thermal decomposition of [Hg(O2CR)2] (1), reacts with Q2[Pd2Cl4(μ-Cl)2] to give [Hg(R)Cl] (3) and Q2[Pd(R)Cl(μ-Cl)]2 (Q = (PhCH2)Ph3P (4a), Me4N (4b)), which react (i) with Tl(acac) (1:2, acac = acetylacetonate) to give Q[Pd(R)Cl(O,O-acac)] (Q = (PhCH2)Ph3P (5a), Me4N (5b)) or (ii) with AgClO4 (1:2) to give [Pd(κ3-R)Cl] (κ3-R = κ3-C6(NO2)2-2,6-(OMe)3-3
通过[Hg(O 2 CR )的热分解获得的络合物[HgR 2 ](R = C 6(NO 2)2 -2,6-(OMe)3 -3,4,5-C 1(2)))2 ](1),与Q 2 [Pd 2 Cl 4(μ-Cl)2 ]反应,得到[Hg(R)Cl](3)和Q 2 [Pd(R)Cl(μ-Cl)] 2(Q =(PhCH 2)Ph 3 P(4a),Me 4 N(4b))),将(i)与Tl(acac)(1:2,acac =乙酰丙酮化物)反应,得到Q [Pd(R)Cl(O,O-acac)](Q =(PhCH 2)Ph 3 P(图5a)中,Me 4 N(图5b))或(ii)与AgClO 4(1:2),得到[钯(κ 3 -R)CL](κ 3 -R =κ 3 -C 6(NO 2)2 -2,6-(OMe)3 -3,4,5-C 1,O,O'(6)),也可以通过5a与HBF 4反应获得。配合物6与对甲苯胺(1:1,L)
