In this case, reaction of hexahedral silsesquioxane and CF 3 SO 3 H in DMSO conducted in 1 : 12 molar ratio gives heptahedral silsesquioxane. In the first step CF 3 SO 3 H acid attacks siloxane Si-O-Si bonds and the formation of Si-O-SO 2 CF 3 bond parallel with cage opening process is observed and compound B is obtained (Figure below). Such an ...
Prostaglandin G 2 (PGG 2) is an organic peroxide belonging to the family of prostaglandins. [1] The compound has been isolated as a solid, although it is usually used in vivo. It quickly converts into prostaglandin H 2, a process catalyzed by the enzyme cyclooxygenase (COX). Prostaglandin G 2 is produced from the fatty acid arachidonic acid.
The conversion from arachidonic acid to prostaglandin H 2 is a two-step process. First, COX-1 catalyzes the addition of two free oxygens to form the 1,2-dioxane bridge and a peroxide functional group to form prostaglandin G 2 (PGG 2). [3] Second, COX-2 reduces the peroxide functional group to a secondary alcohol, forming prostaglandin H 2.
For all A P H 4 systems in D 4h symmetry, the ground state is a 1g. The exact electronic configuration, however, is dependent on the electronegativity of the main group element. The distortion to tetrahedral geometry has b 2u symmetry. For these A P H 4 systems, the a 2u →b 1g * and e u →e g * one-electron charge-transfer transitions are ...
