LiBr is an efficient catalyst for the dihydroxylation of alkenes to afford either syn or anti diols with excellent diastereoselectivity depending upon the use of NaIO4 or PhI(OAc)2 as the oxidants.
L. Emmanuvel, T. M. A. Shaikh, A. Sudalai, Org. Lett., 2005, 7, 5071-5074.


Selective syn and anti diacetoxylations of alkenes have been achieved using a PhI(OAc)2/BF3·OEt2 system in the presence and absence of water, respectively. A broad range of substrates including electron-deficient alkenes furnishes the desired products in good to excellent yields and diastereoselectivity. This novel methodology provides an alternative approach for the preparation of various 1,2-diols.
W. Zhong, J. Yang, X. Meng, Z. Li, J. Org. Chem., 2011, 76, 9997-10004.

 

A one-pot two-step sequence involving an oxidation/imine-iminium formation/reduction allowed the N-alkylation of amines by alcohols. Optically active alcohols and amines can be converted without any epimerization.
C. Guérin, V. Bellosta, G. Guillamot, J. Cossy, Org. Lett., 2011, 13, 3478-3481.


A catalytic Mitsunobu reaction system is described in which the azo reagent is used as an organocatalyst and iodosobenzene diacetate is used as the stoichiometric oxidant. Yields obtained in the catalytic reactions of carboxylic acids and alcohols were slightly lower than those obtained from corresponding stoichiometric reactions.
T. Y. S. But, P. H. Toy, J. Am. Chem. Soc., 2006, 128, 9636-9637.


Phenyliodonium ylides provide easy access to various 1,1-cyclopropane diesters using rhodium or copper catalysis and are safer and convenient alternatives to the corresponding diazo compounds. Moreover, the iodonium ylide of dimethyl malonate was obtained in 78% yield using improved conditions that involve a simple filtration step to isolate the desired product.
S. R. Goudreau, D. Marcoux, A. B. Charette, J. Org. Chem., 2009, 74, 470-473.
