formation of tricarbonyl(tetramethylcyclobutadiene)cobalt hexafluorophosphate and its conversion into the neutral complexes [Co(CO)2(C4Me4)}2] and [Co(CO)2(C4Me4)I] are described. Reaction of the latter with arenes in the presence of aluminium chloride provides a general route to the cations [Co(C4Me4)(arene)]+ of which seven new examples are described. Some carbonyl substitutions of the cation [Co(CO)3(C4Me4)]+
描述了三羰基(四甲基环丁二烯)钴六氟磷酸盐的形成及其向中性络合物[Co(CO)2(C 4 Me 4)} 2 ]和[Co(CO)2(C 4 Me 4)I]的转化。后者在氯化铝存在下与芳烃的反应提供了通向阳离子[Co(C 4 Me 4)(芳烃)] +的一般路线,其中描述了七个新实例。还报道了阳离子[Co(CO)3(C 4 Me 4)] +的一些羰基取代。
