Reactions of a cerium(III) amide with heteroallenes: Insertion, silyl-migration and de-insertion
Yin, Haolin,Carroll, Patrick J.,Schelter, Eric J.
, p. 9813 - 9816 (2016)
Reactions of Ce[N(SiMe3)PhF]3 (-PhF = pentafluorophenyl) toward small molecules of the type E1CE2 (E1, E2 = O, S, NR), including carbon disulfide, carbodiimide, carbon dioxide, isocyanate and isothiocyanate are reported, resulting in distinct products, including cerium(iii) dithiocarbamate, cerium(iii) guanidinate, isocyanates and unsymmetric carbodiimides. These reactions were rationalized as three consecutive stages of the same reaction pathway: insertion, silyl-migration and de-insertion.
Pentafluorophenyl Nitrene: a Matrix Isolated Aryl Nitrene that Does Not Undergo Ring Expansion
Dunkin, Ian R.,Thomson, Paul C. P.
, p. 1192 - 1193 (1982)
Photolysis of pentafluorophenyl azide or pentafluorophenyl isocyanate in low-temperature matrices gives pentaflurophenyl nitrene which, in the presence of CO, may react photochemically but not thermally to give the isocyanate.
Specific inhibitors of puromycin-sensitive aminopeptidase with a 3-(halogenated phenyl)-2,4(1H,3H)-quinazolinedione skeleton

Specific puromycin-sensitive aminopeptidase (PSA) inhibitors with a 3-(halogenated phenyl)-2,4(1H,3H)-quinazolinedione skeleton were prepared and their structure-activity relationships were investigated. The nature (F, Cl or Br), number and position(s) of the halogen atom(s) introduced into the 3-phenyl group were concluded to be critical determinants of the inhibitory activity.
Investigating N-methoxy-N′-aryl ureas in oxidative C-H olefination reactions: An unexpected oxidation behaviour
Willwacher, Jens,Rakshit, Souvik,Glorius, Frank
supporting information; experimental part, p. 4736 - 4740 (2011/08/06)
Herein, we report a urea derived directing group for mild and highly selective oxidative C-H bond olefination. Subsequent intramolecular Michael addition affords dihydroquinazolinones in good yields. The N-O bond of the urea substrate exhibits superior oxidative behaviour compared to a variety of other external oxidants. The Royal Society of Chemistry 2011.
N-(POLYFLUOROARYL)-HIDROXYLAMINES. SYNTHESIS AND PROPERTIES
Miller, A.O.,Furin, G. G.
, p. 247 - 272 (2007/10/02)
Fluorine-containing N-arylhydroxylamines have been obtained by the reaction of hydroxylamine or its N- and O-derivatives on polyfluorinated benzenes and pentafluoropyridine.The influence of fluorine atoms on the reactivity of hydroxylamino group has been investigated.The reaction of N-polyflouroarylhydroxylamines with aldehydes has been shown not to occur, whereas their reaction with nitrosobenzenes leads to azoxybenzenes and with Lewis acids leads to corresponding nitrosobenzenes, azoxybenzenes and anilines.The action of acids on 2,3,5,6-tetrafluorophenylhydroxylamine leads to the acid-catalyzed rearrangement of the latter into 4-amino-2,3,5,6-tetrafluorophenol.C,N-Diarylnitrones have been obtained by the oxidation with MnO2 of fluorine-containing arylhydroxylamines possessing the CH-fragment in an α-position.
