Treatment of [Co2(µ-HOCH2CCCH2OH)(CO)6] in Me2S with HBF4·OEt2 affords the stable salt [Co2(µ-Me2SCH2CCCH2SMe2)(CO)6][BF4]2 which reacts with secondary amines to afford [Co2(µ-R2NCH2CCCH2NR2)(CO)6](R = Et or Ph), while treatment of [Co2(µ-HOCH2CCCH2OH)(µ-dppm)2(CO)2][dppm = bis(diphenylphosphino)methane] with HBF4·OEt2 affords a stable dicarbenium complex [Co2(µ-H2CCCCH2)(µ-dppm)2(CO)2][BF4]2 which forms adducts with pyridine and triphenylphosphine.
用
HBF4-OEt2 处理 Me2S 中的 [Co2(µ-HOCH2CCCH2OH)(CO)6],可得到稳定盐 [Co2(µ-Me2SCH2CCCH2SMe2)(CO)6][BF4]2,该盐与仲胺反应生成 [Co2(µ-R2NCH2CCCH2NR2)(CO)6](R = Et 或 Ph)、而用 -OEt2 处理[Co2(µ-HOCH2CCCH2OH)(µ-dppm)2(CO)2][dppm = 双(
二苯基膦)
甲烷]会得到稳定的二
钡络合物[Co2(µ-H2CCCCH2)(µ-dppm)2(CO)2][BF4]2,该络合物会与
吡啶和
三苯基膦形成加合物。
