Iron(III)-substituted polyoxometalate (TBA)4PFeW 11O39· 3H2O, has been demonstrated as an efficient catalyst in the ring opening of 1,2-epoxides with acetic anhydride for the one-pot synthesis of 1,2-diol esters in high to excellent yields under solvent-free condition. Copyright
Oxidation of Olefins with Benzenetelluric Anhydride

, p. 269 - 272 (1987)
Olefins were found to be oxidized by use of benzenetellurinic anhydride in acetic acid leading to vic-diacetates.Benzenetellurenic acid derivatives formed in situ are suggested as the active species.This diacetoxylation proceeds in net syn fashion probably via anti acetoxytellurenylation of the olefin followed by displacement of the phenyltelluro group by an acetoxy group with inversion.
Vicinal Difunctionalization of Alkenes under Iodine(III) Catalysis involving Lewis Base Adducts

The influence of a 2-pyridinyl substituent on the catalytic performance of aryl iodides as catalyst in iodine(III) chemistry was explored. An efficient Lewis base adduct between the pyridine nitrogen and the electrophilic iodine(III) center was identified and confirmed by X-ray analysis. This arrangement was shown to generate a kinetically competent superior catalyst structure for the catalytic dioxygenation of alkenes. It introduces the concept of Lewis base adduct formation as a kinetic factor in iodine(I/III) catalysis. (Figure presented.).

Paragraph 0035-0043, (2017/05/30)
The invention discloses a preparation method of trans-1,2-cyclohexanol glycol diacetate. The preparation method comprises the following steps: (1) adding trans-1,2-cyclohexanol glycol and an esterification catalyst into a reaction container, then adding a reaction solvent, and heating to ensure that the trans-1,2-cyclohexanol glycol and the esterification catalyst are completely dissolved; (2) heating the reaction solution while stirring to boil the reaction solution, and when an organic phase overflow layered in a refluxing water separator returns to the reaction container, dropwise adding an esterifying agent into the reaction solution, and continuously reacting after dropwise adding the esterifying agent until the esterification reaction is finished; and (3) performing filtration, alkali cleaning, water washing and rectification on a reaction product to obtain the trans-1,2-cyclohexanol glycol diacetate. The preparation method disclosed by the invention is high in yield, low in investment and running costs and simple in production process, and is easy to realize industrial large-scale production.
