Visible light promoted continuous flow photocyclization of 1,2-diketones

The continuous flow Norrish-Yang photocyclization of 1,2-diketones has been developed and used for the synthesis of a large number of functionalized 2-hydroxycyclobutanones, under blue light irradiation and employing acetone as a solvent. This eco-friendly procedure represents a valid alternative to the reactions carried out in batches thus reducing the reaction times, the formation of secondary products and simplifying the purification steps. The use of differently substituted diketone compounds has allowed us to obtain a wide range of 2 and 3-functionalized cyclobutanones, thus allowing the evaluation of the scope and limitations of this procedure.

Titanium-mediated reductive cross-coupling reactions of imines with nitriles: An efficient route for the synthesis of α-aminoketones or 1,2-diketones

The reaction of imines with low-valent titanium species, generated in situ by using Ti(OiPr)4/2 c-C5H9MgCl reagent, affords titanium-imine complex, which can couple with nitriles to provide 2,5-diazatitanacyclop

Ruthenium-catalyzed oxidation of alkenes at room temperature: A practical and concise approach to α-diketones

Chemical equations presented. The catalytic oxidation of alkenes to α-diketones is unprecedented. A new oxidation of alkenes, catalyzed by a ruthenium complex, which allows an efficient route to α-diketones using TBHP as an oxidant is described. This methodology is highly functional group tolerant, is practically convenient, requires no additional ligand, and operates under mild conditions with short reaction times. Based upon experimental observations, a plausible mechanism is proposed.
