Ionic Pathways in the Photochemistry of Cyclic Sulfite Esters

The photochemistry of cyclic carbonate esters proceeds by the photochemical extrusion of carbon dioxide to give 1, 3-diradicals which produce oxiranes as well as other radical derived species. The corresponding cyclic sulfite esters, upon irradiation, give intermediates that are trapped by alcohols yet generate no oxiranes. These results are consistent with ionic intermediates.
Oxidation of alkenes with hydrogen peroxide, catalyzed by boron trifluoride. Synthesis of vicinal methoxyalkanols
Terent'ev,Boyarinova,Nikishin
, p. 592 - 596 (2008/09/20)
In oxidation of alkenes with the BF3-H2O2 system, boron trifluoride induces transfer of available oxygen from hydrogen peroxide, accompanied by the formation of epoxides. The oxidation in methanol occurs as a one-pot two-step process involving epoxidation of the C=C bond followed by opening of the oxirane ring, with the formation of methoxyalkanols.
A simple one-pot synthesis of β-alkoxy alcohols from alkenes
Le Bras, Jean,Chatterjee, Debabrata,Muzart, Jacques
, p. 4741 - 4743 (2007/10/03)
β-Methoxy alcohols are easily obtained from the one-pot reaction of alkenes with oxone in methanol, in the absence of any additive or catalyst. The use of other alcohols as solvents has shown that the efficiency of the process decreases with the steric hindrance of the alcohol.

Methyltrioxorhenium supported on silica tethered with polyethers as catalyst for the epoxidation of alkenes with hydrogen peroxide
Neumann, Ronny,Wang, Tie-Jun
, p. 1915 - 1916 (2007/10/03)
Methyltrioxorhenium has been supported on silica functionalized with polyether tethers; in the absence of an organic solvent, this catalytic assembly catalysed the epoxidation of alkenes with 30% aqueous H2O2 in high selectivity compared to the ring opening products observed in homogeneous media.
FeCl3·6H2O supported on SiO2 catalysed ring opening of epoxides with alcohols, acetic acid, water, chloride, bromide and nitrate ions
Iranpoor, Nasser,Tarrian, Tahere,Movahedi, Zarangiz
, p. 1473 - 1476 (2007/10/03)
FeCl3·6H2O absorbed on chromatographic silica gel can act as an efficient catalyst for alcoholysis, hydrolysis and acetolysis of epoxides. Methanolysis of (R)-styrene oxide proceeds with high stereospecificity and in excellent yield. This catalyst can also convert epoxides to their corresponding β-halohydrins and β-nitrato alcohols in the presence of chloride, bromide and nitrate ions respectively.

, p. 2591 - 2594 (2007/10/03)
The electrochemical transformation of different epoxides to their corresponding β-alkoxy alcohols and diols was achieved by using an electrogenerated acid-catalyst.A competitive ring-opening reaction of activated epoxides in the presence of deactivated epoxides was also successfully carried out in both alcohols and water.

Iranpoor,Salehi
, p. 1152 - 1154 (2007/10/02)
An efficient, catalytic, simple and mild method for the conversion of epoxides into their corresponding β-alkoxy alcohols was performed in primary, secondary and tertiary alcohols and in the presence of catalytic amounts of ferric chloride. The β-alkoxy alcohols were obtained with high stereo- and regioselectivity and in good to excellent yields.
