Morpholine–4-nitrophenol (1/2) [PDF]
Acta Crystallographica Section E Structure Reports Online, 2012 In the title adduct, 2C6H5NO3·C4H9NO, the morpholine ring adopts a chair conformation. The dihedral angle between the two nitro-phenol rings is 69.47 (9)°. The nitro groups attached to the benzene rings make dihedral angles of 3.37 (16) and 3.14 (13)° in the two mol-ecules of nitro-phenol.

ChemSusChem, Volume 18, Issue 6, March 15, 2025.we have developed an electrochemical Ni−H catalyzed arylation coupling method of unactivated alkenes with aryl halides. The method displays broad functional group tolerance and proceeds under very mild conditions. Furthermore, aryl chlorides were also compatible substrates in this catalytic system. This conversion holds significant implications for the

Optimization of diarylazines as anti-HIV agents with dramatically [PDF]
, 2013 Non-nucleoside inhibitors of HIV-1 reverse transcriptase are reported that have ca. 100-fold greater solubility than the structurally related drugs etravirine and rilpivirine, while retaining high anti-viral activity.

ChemSusChem, EarlyView.An efficient, metal‐free electrochemical three‐component reaction of cinnamic acids, SO2, and amines to access (E)‐β‐styryl sulfonamides is reported. Utilizing graphite electrodes and SO2 stock solutions, this decarboxylative protocol proceeds under mild conditions with high regio‐ and stereoselectivity.

European Journal of Organic Chemistry, EarlyView.An ATRA‐based, Ru‐photocatalyzed radical‐polar crossover reaction for the preparation of monoprotected dicarbonyl compounds is reported. This procedure is based on the capture of a cationic intermediate, arising from the radical step, with diverse nucleophiles.

Impact of copper and iron binding properties on the anticancer activity of 8-hydroxyquinoline derived Mannich bases. [PDF]
, 2018 The anticancer activity of 8-hydroxyquinolines relies on complex formation with redox active copper and iron ions. Here we employ UV-visible spectrophotometry and EPR spectroscopy to compare proton dissociation and complex formation processes of the ...

Perfluoroalkylated amphiphiles with a morpholinophosphate or a dimorpholinophosphate polar head group [PDF]
, 1998 Some previously synthesized (perfluoroalkyl)alkyldimorpholinophosphates, CnF2n+1CmH2mOP(O)-[N(CH2CH2)(2)O](2), were found remarkably to stabilize heat sterilizable water-in-fluorocarbon reverse emulsions and to have a strong proclivity to self-aggregate ...

Zeitschrift für Naturforschung B, 1970 The new route to the synthesis of 3-oxo-1,4-oxazines 1 has been extended. N-aryl-N-chloroacetyl-m-nitro-phenacyl amines afford either only oxazine, or beta-lactam or both depending on the nature of the N-aryl substituent. A set of rules indicates from which precursors beta-lactam, as against morpholine formation, may be expected.
