AIEE active perylene bisimide supported mercury nanoparticles for synthesis of amides via aldoximes/ketoximes rearrangement

Aggregates of perylene bisimide (PBI) derivative 3 serve as reactors and stabilizers for the preparation of mercury nanoparticles (HgNPs) which exhibit excellent catalytic efficiency in the conversion of aldoximes/ketoximes into primary/secondary amides via Beckmann rearrangement. This journal is

Cycloadditions of N=S functions to cyclopentadienones

Cyclopentadienones react with EtO2CN=S=O and related N=S reagents to provide ready syntheses of 1,2,5-thiadiazolidines (8, 12, 17), diaminosulfanes (11, 13), an aminocyclopentenone (10) and the first unoxidised 1,2,3-oxathiazolidine (16), all i

Reaction of furans with trithiazyl trichloride: A new synthesis of isothiazoles

Trithiazyl trichloride 1 converts 2,5-diphenylfuran into 5-benzoyl-3-phenylisothiazole 2 regiospecifically and in high yield. This is a new ring opening of furans and a new synthesis of isothiazoles. 2,5-Bis(4-methylphenyl)furan, 3-bromo-2,5-diphenylfuran, 2,3,5-triphenylfuran, 2,5-di-tert-butylfuran and its 3-chloro and 3-bromo derivatives react in an entirely analogous manner to give the corresponding isothiazoles (55-85%) in synthetically useful, one-pot, conversions. 2,5-Diphenylthiophene reacts more slowly with the trimer 1 to give the same product, 2, as the corresponding furan, probably by oxidation of the analogous thiobenzoyl compound by the reagent, which is shown to oxidise thiobenzophenone to benzophenone very rapidly. Tetraphenylcyclopentadienone 8 reacts rapidly with the trimer to give 3,4,5,6-tetraphenyl-2(1H)-pyridone 10 (56%). Possible mechanisms in which the monomer, Cl-S≡N, is the reacting species are proposed for all of these reactions.

An Efficient and Novel Approach to the Synthesis of 3,4,5,6-Tetraphenyl-2(1H)-pyridinone

The reaction of tetracyclone (1a) with sodium azide under acidic conditions was found to give 3,4,5,6-tetraphenyl-2(1H)-pyridinone (2a) in 90percent isolated yield.The reaction does not proceed by a Schmitt mechanism.By adjusting the reaction conditions,
