The ring closing metathesis reaction in the presence of Grubbs catalyst was demonstrated using several ionic liquids to synthesize a range of macrocyclic tetralactones having ring size of 19 to 31 membered with different spacers. The ionic liquid [mmim][PF6] was found to be an excellent solvent and the recovery of the catalyst was demonstrated. X-ray analysis of a representative macrocyclic tetralactone
使用几种离子液体证明了在Grubbs催化剂存在下的闭环易位反应,合成了一系列具有不同间隔基的环尺寸为19-31的大环四内酯。发现离子液体[mmim] [PF 6 ]是极好的溶剂,并且证明了催化剂的回收。还报道了代表性的大环四内酯的X射线分析。
