Diaryl diselenides and related compounds as oxygen-transfer agents
Giurg, Mirosaw,Syper, Ludwik
, p. 970 - 985 (2008)
The progress in application of diaryl diselenides and related compounds as transfer agents is presented. The review is limited to the diaryl diselenides having electron-withdrawing substituents, such as nitro, trifluoromethyl, carbamoylphenyl, and polymeric diselenides PADS and PPDS. The methods of their synthesis are described. These compounds are used as effective catalyst for a simple and multi-electron hydroperoxide oxidation of different organic compounds. Transformation of functional groups, cycloalkanones ring contraction, cyclocondensation and degradation of electron-rich arenes is described. Mechanisms of the reactions involved Se(II) and Se(IV) intermediates are discussed.
Photoregulation of Gene Expression with Amantadine-Modified Caged siRNAs through Host–Guest Interactions

RNA interference is an essential and powerful tool for targeting and verifying specific gene functions. Conditional control of small interfering RNA (siRNA) activity, especially using light activation, is a potential method for regulating target gene expr
Cyclopropenone catalyzed substitution of alcohols with mesylate ion
Nacsa, Eric D.,Lambert, Tristan H.
supporting information, p. 38 - 41 (2013/03/28)
The cyclopropenone catalyzed nucleophilic substitution of alcohols by methanesulfonate ion with inversion of configuration is described. This work provides an alternative to the Mitsunobu reaction that avoids the use of azodicarboxylates and generation of hydrazine and phosphine oxide byproducts. This transformation is shown to be compatible with a range of functionality. A cyclopropenone scavenge strategy is demonstrated to aid purification.
