The potassium of the 2,4-di(t-butyl)pentadienyl anion may be prepared by metallation of the corresponding 1,3-diene. This anion reacts readily with titanium, chromium, and zinc dichloride complexes to yield the appropriate M[2.4-(t-C4H9)2C5H5]2 species, which display significant differences relative to their 2,4-dimethylpentadienyl analogs.
2,4-二(叔丁基)戊二烯基阴离子的钾可以通过相应的1,3-二烯的金属化来制备。该阴离子容易与钛,铬和二氯化锌络合物反应,生成适当的M [2.4-(tC 4 H 9)2 C 5 H 5 ] 2物种,相对于它们的2,4-二甲基戊二烯基类似物,它们显示出显着差异。
