摘　　要：采用4′-(4-吡啶基)-2,2′∶6′,2″-三联吡啶和MnCl2制备出线型Mn(Ⅱ)配位聚合物,并将这类基于三齿配体形成的配位聚合物用于催化t-BuOOH氧化苄基仲醇。结果表明,该催化体系中乙腈为最适宜溶剂;催化量的碱对反应有显著促进作用。该方法可以用于氧化不同类型的苄基仲醇,底物范围广;80℃下反应3~5 h,13种具有不同结构的底物均获得较高转化率(95%~99%)和收率。催化剂重复利用4次后仍保持较高的催化效率。Linear Mn(Ⅱ)coordination polymer is prepared from 4′-(4-pyridyl)-2,2′∶6′,2″-terpyridine and MnCl_(2),and used to catalyze the oxidation of benzyl secondary alcohols by t-Bu OOH.Results show that acetonitrile is the most suitable solvent in the catalytic system;Catalytic amount of base can significantly promote the reaction.This method can be used to oxidize different types of benzyl secondary alcohols with a wide range of substrates.After reaction has performed at 80℃ for 3-5 hours,excellent conversions(95%-99%)and high yields of 13 substrates with different structures are obtained.The catalyst still remains a high catalytic efficiency after 4 times of reuses.
