Reaction of nickelocene with bis(trifluoromethyl)diazomethane affords a complex which is formulated as a 1 : 2 adduct. A possible structure is discussed. Tricarbonyl(π-vallyl, π-2-methylallyl, or π-1-methylallyl)cobalt react at room temperature with (CF3)2CN2 to form 1:1 adducts [[graphic omitted]:CH2(CO)3], [[graphic omitted]:CH2(CO)3], [[graphic omitted]CHMe(CO)3], and [[graphic omitted]CH2(CO)3];
镍茂与双(三氟甲基)重氮甲烷的反应提供了配合物,其被配制成1:2的加合物。讨论了一种可能的结构。三羰基(π-戊烯丙基,π-2-甲基烯丙基或π-1-甲基烯丙基)钴在室温下与(CF 3)2 CN 2反应形成1:1加合物[[未显示图形]:CH 2(CO)3 ],[[省略图形]:CH 2(CO)3 ],[[省略图形] CHMe(CO)3 ]和[[省略图形] CH 2(CO)3 ]。后者是次要产品。这些物质与Ph 3 P或Ph 3 As反应导致一氧化碳的置换。
