2-C(2)B(10)H(11) tag and 10 with an ionic [nido-7,8-C(2)B(9)H(11)](-) tag were synthesized. Both 9 and 10 are highly reactive catalysts for olefin metathesis reactions. Importantly, 10 is a robust and recyclable anion-appended catalyst that was suitable for noncovalent binding with many cationic resins. At least ten recycles were achieved for RCM of the selected substrate using 10 as the catalyst in ionic liquids
钌卡宾配合物9与closo-1,2-C(2)B(10)H(11)标签和10与离子[nido-7,8-C(2)B(9)H(11)] (-)标签被合成。9和10都是烯烃复分解反应的高反应性催化剂。重要的是,10是一种坚固耐用且可循环使用的阴离子加成催化剂,适用于与许多阳离子树脂进行非共价结合。使用10种离子液体中的催化剂,对所选底物的RCM至少实现了10次循环。
