The chemistry of an isolable azomethine ylide

The 4-isoxazoline 3 undergoes ring contraction to the acylaziridine 5 which is converted to the azoraethine ylide 4. The small influence of solvent polarity on the rate constant of the conversion 3 ? 4 suggests a mechanism via a trimethylene type species for the rate-determining step. Whereas 4 is the first azomethine ylide which can be isolated without being stabilized by aromatic resonance, the ylides 20-22 dimerize to piperazine derivatives. 1,3-Dipolar cycloadditions of the azomethine ylides 4 and 20-22 are described.

Reduction of Heterocyclic Compounds. II. Reduction of Heterocyclic Compounds with Sodium Borohydride – Transition Metal Salt Systems

The reduction of heterocyclic compounds with the sodium borohydride-transition metal salt system was investigated.Among transition metal salts examined in this system, the sodium borohydride-nickelous chloride system was found to exhibit the strongest reducing activity.Quinoline, isoquinoline, quinoxaline and their derivatives were reduced with this system to give the corresponding tetrahydro derivatives.Keywords: reduction; sodium borohydride-nickelous chloride system; sodium borohydride; transition metal salt; 1,2,3,4-tetrahydroquinoline; 1,2,3,4-tetrahydroisoquinoline; 1,2,3,4-tetrahydroquinoxaline.

Excited-State Proton Transfer in Thiazolo-[4, 5-d]thiazo Heterocyclic Systems and the Geometry Alterations’ Effect on Photophysical Characters: A Theoretical Study

Thiazolo-[4,5-d]-thiazo-frame (tztz) compounds are important heteroaromatic organic systems, which recently became a subject of several studies in the field of organic electronics and organic photovoltaics. The most important physical nature of these systems is reported to be an equilibrium between enol and keto forms following excited-state proton transfer. This process originates from a flat trend of the S1 PE (potential energy) profile along the proton transfer coordinate. In the present work, we determined and interpreted the excited-state proton transfer and photophysical nature of these systems extensively by means of the MP2/CC2 and CASSCF theoretical approaches. Also, the effects of amine (-NH2) and cyano (-CN) substitutions were taken into account comprehensively by considering the transition energies and proton transfer pathways of the resulting tztz derivatives. It has been predicted that the physical nature of the excited-state intramolecular proton transfer, as the main character of these systems, is being affected significantly by substitutions. For all of the considered tztz derivatives, a conical intersection (CI) between ground and the S1 excited state was predicted. This CI makes the considered species capable to be responsible for photochromism and photoswitching as well.

Tertiary amine oxidation using HOF-CH3CN: A novel synthesis of N-oxides

HOF·CH3CN, probably the best oxygen transfer agent organic chemistry has to offer, is easily made by bubbling diluted fluorine (10-15%) through aqueous acetonitrile solution. Used as formed without any isolation or purification, it reacts with various tertiary amines such as pyridine derivatives, polyaromatic nitrogen containing compounds and aliphatic and alicyclic ones to form the corresponding N-oxides. When two nitrogen atoms are present it is possible to make both the N-monoxides and the N,N-dioxides. The reaction times are short (a few minutes), conditions are very mild (0-25 C) and the yields range from good to excellent (70-95%).

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Reference of 1532-72-5. In my other articles, you can also check out more blogs about 1532-72-5
