Manganese(II)/Picolinic Acid Catalyst System for Epoxidation of Olefins
Moretti, Ross A.,Du Bois,Stack, T. Daniel P.
supporting information, p. 2528 - 2531 (2016/07/06)
An in situ generated catalyst system based on Mn(CF3SO3)2, picolinic acid, and peracetic acid converts an extensive scope of olefins to their epoxides at 0 °C in 5 min, with remarkable oxidant efficiency and no evidence of radical behavior. Competition experiments indicate an electrophilic active oxidant, proposed to be a high-valent Mn = O species. Ligand exploration suggests a general ligand sphere motif contributes to effective oxidation. The method is underscored by its simplicity and use of inexpensive reagents to quickly access high value-added products.
Practical synthesis of (E)- and (Z)-2-silyl-3-penten-1-ols with high enantiopurity
Fukuda, Koichiro,Miyashita, Masaaki,Tanino, Keiji
experimental part, p. 4523 - 4525 (2010/10/02)
Practical methods for the synthesis of the optically active (E)- and (Z)-2-silyl-3-pentene-1-ols are described. The optically pure (E)-allylsilane was synthesized from commercially available (R)-3-butyn-2-ol in five steps involving hydrozirconation follow
The Regiochemistry and Stereochemistry of the Hydroboration of Allylsilanes
Fleming, Ian,Lawrence, Nicholas J.
, p. 3309 - 3326 (2007/10/02)
The hydroboration of a wide range of allylsilanes 3 and 5-21 is found to be generally regioselective for attachment of the boron to C-3 and hydrogen to C-2 of the allyl unit, and to be generally stereoselective in the sense 1, with attachment of the boron
