Catalyst-free photooxidation of triarylphosphines under aerobic conditions

Photoinduced Pyramidal Inversion Behavior of Phosphanes Involved with Aggregation‐Induced Emission Behavior

“…It has long been known that phosphines are easily photooxidized in the air. [56][57][58] During the prolonged photoirradiation to the solution after disappearance of the CD intensity, the absorption spectra slightly changed (Figures 2d-f), which was attributed to the formation of phosphine-oxides (1aoxide, 1b-oxide, and 1c-oxide). It was supported by NMR and 31 P NMR spectra (Figures S4-S6).…”

Nano-Au/MCeOx Catalysts for the Direct Oxidative Esterification of Methylacrolein to Methyl Esters

“…Currently, esters are mainly produced by the acetone cyanohydrin process. , The method needs a multistep process, which produces the acids or their derivatives. It not only corrodes the equipment but also yields a large amount of byproducts . Therefore, it is particularly important to develop a green production line for methyl methacrylate (MMA).…”

“…It not only corrodes the equipment but also yields a large amount of byproducts. 4 Therefore, it is particularly important to develop a green production line for methyl methacrylate (MMA). Without adding any toxic or corrosive compounds, oxidative esterification of methylacrolein (MAL) with methanol to MMA is a green and sustainable production method.…”

Visible light induced oxidative hydroxylation of boronic acids

“…After hydrolysis, phenol or alcohol would be formed as the final product (Scheme 1b). [28][29][30][31][32][33][34][35][36][37] With our continues research interest in aerobic photo oxidation reactions, [38][39][40][41] we turned our interest to study thioxanthone as catalyst for this transformation. Thioxanthone was normally used as photo initiator in polymer chemistry.…”
