catalyze hydrogenation reactions subsequent to ring closing olefin metathesis. Under these conditions, hydrogenation of cyclopentenols proceeds smoothly at ambient temperature and under 1 atm of hydrogen in toluene. An alternative protocol was developed that involves the formation of hydrogen in situ by reaction of excess sodium hydride with protic functional groups and water.
在闭环烯烃复分解之后,氢化钠激活钌卡宾配合物以催化氢化反应。在这些条件下,环戊烯醇的氢化在环境温度和氢气在1 atm的甲苯中平稳进行。已开发出另一方案,该方案涉及通过过量的氢化钠与质子官能团和水反应原位形成氢。
