Me2C= CMe2，在0℃下每小时催化循环高达4000次。这些研究还分离出了第一个二氢烯烃配合物，催化中的活性中间体，以及在催化剂失活时形成的一些不寻常的氢桥簇配合物。铱基体系的高催化活性可能令人惊讶，因为之前发现第三行过渡金属的催化活性低于第一行，尤其是第二行（见图1）。一个字符,
Me2C= CMe2, at up to 4000 catalytic cycles per hour at 0 C. These studies have also led to the isolation both of the first dihydridoolefin complexes, the active intermediates in catalysis, and of some unusual hy-drogen-bridged cluster complexes formed in the deactivation of the catalysts. High catalytic activity in an iridium-based system might be thought surprising, because transition metals of the third row had previously been found to be less active in catalysis than those of the first and, more especially, the second rows(see Figure 1).
