The bistriflate complex [1,4-Pt(MeCN)}2C6(CH2NMe2)4-2,3,5,6}](OTf)2, 14a, has also been used for the synthesis of the organometallic polymer [1,4-PtI(μ-I)}2C6(CH2N(H)Me2)4-2,3,5,6}]n}(OTf)2n, 24. Triflate complex 14a slowly reacts with iodomethane to afford the dark red air-stable crystalline complex [1,4-PtI}2C6Me-1-(CH2NMe2)4-2,3,5,6}](OTf), 23. The X-ray molecular structure of 23 shows it
新的配体前体[1-(Me 3 Si)-4-(R)C 6(CH 2 NMe 2)4 -2,3,5,6}](2,R = Me 3 Si; 3,R = H)已用于制备离子性1,4-亚苯基桥连的双钯(II)和钯(II)-铂(II)配合物[1- M(MeCN)}-4- M'(MeCN )} C 6(CH 2 NMe 2)4 -2,3,5,6}](BPh 4)2(5b,M = M'= Pd; 10,M = Pd,M'= Pt)。新配体前体C 6 Br 2(CH2 NME 2)4 -2,3,5,6-,11,生成想必聚合organodilithium试剂,12,其在与转移金属化反应[氯铂酸2(ET 2 S)2 ],得到1,4-亚苯基-桥连的双铂络合物[1,4-(PtCl)2 C 6(CH 2 NMe 2)4 -2,3,5,6}],13。无色的反应13与SO 2,得到独特的橙色双- SO 2加合物[1
