the products arose from a loss of the methyl group attached to the central pyrrole ring N atom. When the reduction was carried out in DME as a solvent, the complex [2,5-[(C4H3N)CPh2]2[C4H2N(Me)]}Th(OMe)]2(m-OC2H4OMe)2}· 0.75(hexane) (5) was isolated. This species is derived from two different pathways of C−O cleavage of the DME solvent. Reduction of 2,5-[(C4H3N)CPh2]2[C4H2N(Me)]}ThCl(C4H3N)CPh2[C4H3N(Me)]}
三吡咯化物二价阴离子2的四价络合物[2,5-[(C 4 H 3 N)CPh 2 ] 2 [C 4 H 2 N(Me)]} ThCl 2(THF)] THF(2)的还原取决于反应条件,1,2,5 -[(C 4 H 3 N)CPh 2 ] 2 C 4 H 2 N(Me)提供不同的产物。在每种情况下,反应都是通过最初形成还原的物种而进行的,这是由暗红色的快速形成,然后缓慢而完全的变色所表明的。在减少甲苯的情况下,络合物(2,5-[(C 4H 3 N)CPh 2 ] 2 [C 4 H 2 N]} 2 Th [K(甲苯)] 2)·1.5(甲苯)(3a)和2,5-[(C 4 H 3 N)CPh 2取决于结晶溶剂(甲苯对DME),得到] 2 [C 4 H 2 N]} 2 Th [K(DME)] 2(3b)。在这两种情况下,产物都是由于连接在中心吡咯环N原子上的甲基的损失而产生的。当在DME作为溶剂进行还原时,络合物[2
