中文摘要：

石蜡在 polyolefins 和好化学药品的合成发现普遍应用。与对石蜡的一个增加的要求，为链烷除氢作用的技术引起了许多注意。异构的催化剂的几种类型为轻链烷的除氢作用在工业发现了应用，主要乙烷，丙烷，和钢瓶煤气。在过去的三十年，很多转变金属建筑群，特别地绑扎 pincer 的铱建筑群，为链烷除氢作用作为同类的催化剂被开发了。同类的催化剂系统与异构的系统相比在温和得多的条件下面操作，并且一些系统比钢瓶煤气长在链烷的除氢作用展出好活动和高 regioselectivity。

英文摘要：

Olefins find widespread applications in the synthesis of polyolefins and fine chemicals. With an increasing demand for olefins, the technologies for alkane dehydrogenation have drawn much attention. Several types of heterogeneous catalysts have found applications in industry for the dehydrogenation of light alkanes, mainly ethane, propane, and butane. In the past three decades, a number of transition-metal complexes, particularly pincer-ligated iridium complexes, have been developed as the homogeneous catalysts for alkane dehydrogenations. The homogeneous catalyst systems operate under much milder conditions compared with the heterogeneous systems, and some systems exhibit good activity and high regioselectivity in dehydrogenation of alkanes longer than butane.
