weakly ligated, transition metal compounds, [Pd(MeCN)4](BF4)2 (1); [M(MeCN)6](BF4)2, (M Ni, 2; Co, 3); [M(NO)2(MeCN)4](BF4)2, (M Mo, 4; W, 5), vis-à-vis olefins and strained ring compounds was studied. A number of these species were observed to form a charge-transfer complex with tetra-p-anisylethylene. These compounds were also found to catalyze the skeletal rearrangement and polymerization of appropriately
阳离子,弱连接的过渡金属化合物[Pd(MeCN)4 ](BF 4)2(1)的反应活性;[M(MeCN)6 ](BF 4)2,(MNi,2 ; Co,3); 研究了[M(NO)2(MeCN)4 ](BF 4)2,(MMo,4 ; W,5),相对于烯烃和应变环化合物。观察到许多这些物种的以形成具有四-一个电荷转移络合物p-茴香基乙烯。还发现这些化合物催化适当取代的烯烃和环丙烷的骨架重排和聚合。这些反应似乎是由烯烃的π键或小环化合物的应变CCσ键的亲电裂解引起的。
