Reaction of trans -[(2-Me 2 NCH 2 C 6 H 4 2 Pt II ] with Tl III (O 2 CR) 3 (R = Me, i-Pr) gave direct elimination of Tl I (O 2 CR) and formation of the oxidative addition product [(2-Me 2 NCH 2 C 6 H 4 ) 2 Pt IV (O 2 CR) 2 ], in two isomeric forms. A structure with the carbon ligands in trans positions is proposed for the main isomer, whereas the second isomer has the nitrogen ligands in trans positions
6-(Me 2 NCH 2)2 C 6 H 3} Pt(O 2 CR)2 Br],消除了Tl I(O 2 CR),并在两个金属中心之间交换了溴原子和羧基。对于R = Me,已用化学计量比[2,6-(Me 2 NCH 2)2 C 6 H 3} Pt(O 2 CMe)] 2·Tl(O 2 CMe)]·2H 2 O分离出一种产物,这是上述反应的某些产物的加合物。已观察到加成物形成是[2,6-(Me 2 NCH 2)2 C 6 H 3} Pt(O 2 CR)]和Tl(O 2 CR)3的唯一反应,导致[2, 6-(me 2 NCH 2)2 C 6 H 3} Pt(O 2 CR)·Tl(O 2 CR)3]。顺式[[(2-Me 2 NCH 2 C 6 H 4)2 Pt]和顺式[[(2-Me 2 NC 6 H 4 CH 2)2 Pt)]与Tl III(O 2 CR)3的反应与Hg II(O 2 CR)2的相应反应相比,(R
