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.
Synthesis of Cyclic Organic Carbonates from C3-C16 Epoxides

, p. 842 - 843 (2007/10/03)
Cyclic organic carbonates were prepared from epoxides (derivatives of C3-C16 olefins, C4 and C8 dienes, styrene; epichlorohydrin) in the presence of a catalytic system consisting of CoCl2 · 6H2O and dimethylformamide.
DIRECT LIQUID-PHASE OXIDATION OF 3-METHYLBUT-1-ENE BY ATMOSPHERIC OXYGEN

An examination has been made of different variants of the direct oxidation of 3-methylbut-1-ene by atmospheric oxygen in the liquid phase.The most promising of the variants examined for the oxidation of this α-isoamylene is direct oxidation in the presence of a bimetallic catalytic system.Target products were isolated from the oxidate - 3-metyhylbut-1-ene oxide and dimethylvinylcarbinol of sufficient purity.
