  摘要：

  已经开发出四氯化钒（IV）四苯基卟啉和氯化四苯基卟啉铬（III）作为醇的无受体脱氢催化剂。该催化剂已被用于由多种醇和胺以良好的总收率直接合成亚胺。提出通过金属-配体双功能途径进行转化，其中两个氢原子从醇到金属卟啉配合物的外球转移。结果表明，钒和铬催化剂也可用于醇的脱氢并释放出氢气，并且它们可能是其他基于地球金属的催化剂的有价值的替代品。

  In the present work, the catalytic activity of high-valent tetraphenylporphyrinatovanadium(IV) trifluoromethanesulfonate, [V-IV(TPP)(OTf)(2)], in the acetylation of alcohols and phenols with Ac2O is reported. This new V(IV) catalyst was used as an efficient catalyst for not only primary alcohols (benzylic and aliphatic) but also sterically-hindered secondary and tertiary alcohols with acetic anhydride and the corresponding acetates were obtained in 85-99% yield and 0.5-15 min. Acetylation of phenols with acetic anhydride was also performed to afford the desired acetates in 88-99% and 1.5-20 min. This catalyst can be reused several times without loss of its catalytic activity. (C) 2011 Elsevier B. V. All rights reserved.

  In this work, the catalytic activity of high-valent tetraphenylporphyrinatovanadium(IV) trifluoromethanesulfonate, [V-IV(TPP)(OTf)(2)], in the nucleophilic ring-opening of epoxides is reported. This new V(IV) catalyst was used as an efficient catalyst for alcoholysis with primary (methanol, ethanol and n-propanol), secondary (iso-propanol) and tertiary alcohols (tert-butanol), hydrolysis and acetolysis of epoxides with acetic acid and also for the conversion of epoxides to 1,2-diacetates with acetic anhydride, conversion of epoxides to thiiranes with ammonium thiocyanate and thiourea, and for conversion of epoxides to acetonides with acetone. The catalyst was reused several times without loss of its activity. (C) 2011 Elsevier Ltd. All rights reserved.
