The reaction of Mo(diglyme)(CO)3 with K(2,4-C7H11) leads to an exchange of the two organic ligands, yielding K(diglyme)+Mo(2,4-C7H11)(CO)3-. This has been found to be a convenient precursor to other (pentadienyl)molybdenum carbonyl complexes. Thus, reactions with Hg(CN)2, AgI, and I2 lead respectively to Hg[Mo(2,4-C7H11)(CO)3]2, [Mo(2,4-C7H11)(CO)3]2, and Mo(2,4-C7H11)I(CO)3. On the other hand, reactions
Mo(diglyme)(CO)3与K(2,4-C 7 H 11)的反应导致两个有机配体的交换,从而生成K(diglyme)+ Mo(2,4-C 7 H 11) (CO)3 - 。已经发现这是其他(戊二烯基)钼羰基钼络合物的便利前体。因此,与Hg(CN)2,AgI和I 2的反应分别导致Hg [Mo(2,4-C 7 H 11)(CO)3 ] 2,[Mo(2,4-C 7 H 11) (CO)3 ] 2和Mo(2,4-C 7H 11)I(CO)3。另一方面,与CH 3 I或C 2 H 5 I的反应导致偶联反应,其中由羰基配体和CH 3或C 2 H 5基团产生的酰基片段已偶联至2,4-C 7 H 11配体,导致羰基的正式三烷基化并形成醇盐配合物,此后二聚。此外,钼(2,4--C的反应7 ħ 11)(CO)3 -与IC 2 ħ 4我导致了一种双金属物种,其中一个2,4-C 7 H 11配体失去了两个氢原子,从而生成Mo
