  known that the liquid-phase homogeneous unmodified rhodium catalysed hydroformylation of alkenes is poisoned by the presence of trace quantities of conjugated dienes. Nevertheless, some hydroformylation of conjugated dienes is possible with unmodified rhodium, and this reaction is in general slower than alkene hydroformylations at comparable reaction conditions. In the present contribution, we examined

  众所周知，液相的均相未改性铑催化的烯烃加氢甲酰化会因存在痕量的共轭二烯而中毒。然而，在未改性的铑条件下，共轭二烯的加氢甲酰化反应还是可能的，而且在可比的反应条件下，该反应通常比烯烃的加氢甲酰化反应慢。在本贡献中，我们检查（A）烯烃的痕量的存在下催化性能的共轭二烯的杂质和（B）的各种使用铑二烯烃的催化行为4（CO）12在ñ -己烷溶剂中在293度在1.0-4.0 MPa CO和0.5-2.0 MPa H 2下。分析方法是原位高压红外光谱法。观察到（I）在有毒烯烃的加氢甲酰化中，大多数铑在这种竞争情况下与痕量的共轭二烯发生反应，而不与烯烃发生反应；以及（II）各种二烯加氢甲酰化的金属羰基光谱非常相似。在共轭二烯的加氢甲酰化中观察到的一次吸光度最大值出现在大约2109、2091、2087、2064、2049、2037、2030、2020、2012、1999和1990 cm -1。给出铑的已知化学
