Photooxygenation

According to the IUPAC, the photooxygenation is the incorporation of molecular oxygen into a molecular entity. In this video you will see the photooxygenation of cyclopentadiene.

Titanium-Mediated Cyclopropanation on Diesters: Mechanistic Study on the Dramatic Effects of Selected Parameters

Mouhamad Jida, Xavier Gaucher, Jean Ollivier Synlett 2010, 1627-1630 [PDF]

Competitive reactions of diisopropyloxy(η2-alkene)titanium on N-allyl diesters derived from natural amino acids and performed under varying conditions (temperature, nature, and concentration of Grignard reagents) show different regio- and chemoselectivities. In light of the isolated reaction products, a possible mechanism of the formation of original products is discussed.
