Reaction of hydridocarbonylmanganese(I) with perfluorocyclopentadiene at room temperature gives three crystalline 1:1 adducts: pentacarbonyl-σ-(trans-2H-hexafluorocyclopent-3-enyl) manganese by 1,2-addition, pentacarbonyl-σ-(4H-hexafluorocyclopent-1-enyl) manganese by 1,4-addition followed by a 1,3-fluorine shift, and pentacarbonyl-σ-(5H-hexafluorocyclopent-1-enyl) manganese by 1,2-addition followed
氢化羰基锰(I)与全氟环戊二烯在室温下反应生成三种结晶的1:1加合物:五羰基σ-(反式-2 H-六氟环戊-3-烯基)锰加1,2-加成,五羰基-σ-(4 H -6-六氟环戊-1-烯基)锰,然后加1,3-氟,和五羰基-σ-(5 H-六氟环戊-1-烯基)锰,再加1,2-,然后加1 ,3-氟转移。甲酮复杂pentacarbonyl- σ - (4- ħ -tetrafluorocycloent -1-烯-3-只)的混合物在低产量也得到锰。在–78°下反应生成五羰基σ-(4 H-六氟环戊-2-烯基)锰为主要产物,是通过1,4-加成而没有重排而形成的。这些化合物的特征在于降解和光谱方法。
