The carbonyl-carbon kinetic isotope effect (KIE) and the substituent effect were measured for the reaction of phenylthiomethyllithium (PhSCH(2)Li, 1) with benzaldehyde and benzophenone, and cyanomethyllithium (NCCH(2)Li, 2) with benzaldehyde, and the results were compared with those for other lithium reagents such as MeLi, PhLi, CH(2)=CHCH(2)Li, and CH(2)=C(OLi)C(CH(3))(3). It was previously sh...

Green leaf bug Apolygus lucorum (Meyer-Dür) is one of the major pests in agriculture. Management of A. lucorum was largely achieved by using pesticides. However, the increasing population of A. lucorum since growing Bt cotton widely and the increased awareness of ecoenvironment and agricultural product safety makes their population-control very challenging. Therefore this study was conducted to...

Rhodotorula graminis utilized DL-mandelate, L(+)-mandelate, and D(-)-mandelate as sole sources of carbon and energy. Growth on these aromatic substrates resulted in the induction of an NAD-dependent D(-)-mandelate dehydrogenase and a dye-linked L(+)-mandelate dehydrogenase, each catalyzing the stereospecific conversion of its respective enantiomer of mandelate to benzoylformate. Benzoylformate ...

The amino acid-catalysed retroaldol condensation previously described for citral has been extended to other α,β-unsaturated aldehydes. In the presence of glycine and an elevated pH, six other α,β-unsaturated aldehydes also underwent retroaldol condensation. Crotonaldehyde, as well as its proposed intermediate, aldol, were converted into acetaldehyde. Hexenal, decenal, methyl crotonaldehyde, far...

since measurements of O2 uptake with intact bacteriaor extracts indicated approximately the same ratio of activities. Further, bacteria growing on D(-)-mandelate did not accumulate benzaldehyde, which shows that D(-)-mandelate dehydrogenase, rather than benzaldehyde dehydrogenase I (Cook et al., 1975), was now rate-limiting. D(-)-Mandelate dehydrogenase resembles L(+)-mandelate dehydrogenase in...

Catalytic oxidation of styrene has attracted extensive attention in industries and academia. Benzaldehyde, one the derived valuable aromatic aldehyde products, been extensively applied perfume, pharmacy, dye industries. However, it is difficult to achieve a high yield by transforming into benzaldehyde with sustainable supply active catalysts. Furthermore, conventional catalyst species inevitabl...

Abstract Selective photooxidation of aromatic alcohols to corresponding aldehydes is a widely used model reaction for evaluation performance heterogeneous photocatalysts. A top example the photocatalytic production hydrogen peroxide via reduction dioxygen with concomitant benzyl alcohol benzaldehyde. Herein we demonstrate ability benzaldehyde promote auto‐photocatalytic oxidation and produce la...
