结果表明，它们均是有效的硅氢化催化剂，并具有某些独特的催化性能，如在催化苯乙烯的硅氢加成时，以高达85％-100％的区域选择性得到α-加成物。

Hydrocortisone is widely used in patients with septic shock even though a survival benefit has been reported only in patients who remained hypotensive after fluid and vasopressor resuscitation and whose plasma cortisol levels did not rise appropriately after the administration of corticotropin.

1月10日《新英格兰医学杂志》报道，Hadassah希伯来大学医学中心等地的研究人员证实，无论是对所有的脓毒性休克患者还是只针对那些对促肾上腺皮质激素无反应的患者，氢化可的松都不能改善生存率或逆转休克症状；但是，对于已经逆转了休克进程的患者来说，氢化可的松可以加快休克的恢复。

Via comprehensive computations, the possibilities of vinylidene and allene intermediates were excluded, and the reaction mechanism was found to contain the following three steps:(1) gold-catalyzed cyclization to give the cyclic intermediate,(2) the cyclic intermediate undergoing a 1,3-H migration to give a more stable intermediate, with the assistance of water-cluster,(3) finially, the 1,2-H or 1,2-silyl migration occuring for generation of the observed product.

通过对各种可能的反应路径的进行计算和比较，排除了亚甲基卡宾和连二烯中间体的可能性，并确定该异构化反应机理包含以下三个步骤：（1）炔丙基吡啶反应在金催化条件下发生分子内的成环得到环状中间体；（2）环状中间体在水分子簇的协助下优先发生1，3-氢迁移反应，异构化得到更为稳定的中间体；（3）最后再进行1，2-氢迁移或是1，2-硅烷基团迁移即得到实验中所观察到的环异构化产物。
