compounds [W(η-C5H5)2(COMe)H] or [W(η-C5H5)2C6H4(COPh-p)H] respectively. These compounds in carbon tetrachloride give the chloro-analogues [W(η-C5H5)2(COMe)Cl] and [W(η-C5H5)2C6H4(COPh-p)}Cl]. The molybdenum tetramer with carbon monoxide gives both the monocarbonyl [Mo(η-C5H5)2(CO)] and the cyclopentenyl compound [Mo(η-C5H5)(η3-C5H7)2(Co)2] The products of reaction between the dihydrides [M(η-C5H5)2H2]
所述dihydrides [M(η-C 5 H ^ 5)2 ħ 2 ](M = Mo或W),其与
正丁基锂的
甲苯,得到四聚体反应[M(η-C 5 H ^ 5)2 HLI} 4 ]。该四聚体与物理信道反应2 Br或PhCOX [X =
氯,OMe或(M = W)H]得到[M(CH 2 PH)2(η-C 5 H ^ 5)2 ]或[M(η-C 5 H 5)2(
COPh)H]。用
二氧化碳monocarbonyls [M(η-C 5 H ^ 5)2(CO)]以高收率形成。四聚体(M = W)反应与
乙酰氯或
二苯甲酮给予化合物[W(η-C 5 H ^ 5)2(COME)H]或[W(η-C 5 H ^ 5)2 C 6 H ^ 4(
COPh- p)H]。这些化合物在
四氯化碳得到
氯类似物[W(η-C 5 H ^ 5)2(COME)CL]和[W(η-C 5 H ^ 5)2 C 6 H ^ 4(
COPh- p)}
