Efficient conversion of hydrazines to azides with clay-supported ferric nitrate

Can clay emit light? Ru(bpy)32+-modified clay colloids and their application in the detection of glucose

“…Since the work pioneered by Van Damme and coworkers [1,2] and Bard and coworkers [3,4], clays and their modified electrodes (CME) have stimulated a vast body of research on their electrochemistry [5][6][7] and photoelectrochemistry [1,[8][9][10] and applications in chemical and biochemical analyses [11][12][13][14][15]. Recently we reported several photocatalytic systems based on the iron-containing clay colloids (montmorillonite K10) and photosensitizers, like 10-methylacridinium and cyanoanthracenes.…”

A Convenient and Efficient One-Pot Synthesis of 3-Acylisoxazoles Using Iron(III) Salts

“…In addition, the reaction using ammonium iron(III) sulfate gave the corresponding isoxazole derivative 2 in 51% yield, however, in the case of FeO(OH) as the oxidant, only trace amounts of the isoxazole derivatives were obtained (Table 4, entries 13 and 14). On the other hand, the use of iron(II) chloride gave the isoxazole derivative 2 in low yields of 10-19% (Table 4, entries [15][16][17][18][19][20]. Increasing of the amount of iron(II) chloride did not accelerate the formation of isoxazole derivative, but escalated the side reactions to nitroolefin and nitro-alcohol.…”

“…18 In this paper, we would like to propose a convenient and efficient one-pot synthesis of 3-acylisoxazoles using iron(III) salts: iron(III) nitrate under reflux and iron(III) chloride-nitrogen dioxide (NO 2 ) at room temperature. In addition, to increase the reactivity and to shorten the reaction time, a microwave-assisted reaction was developed.…”

TfNN15N: A γ-15N-Labeled Diazo-Transfer Reagent for the Synthesis of β-15N-Labeled Azides

“…However, unlike aryl or carbonyl hydrazine, alkyl hydrazine has the limitation that it cannot be rearranged through nitrosation to produce azides. 12 …”

“…The IR spectrum of PyrNN 15 N was still complex, due to Fermi resonance, but those of Pyr 15 NNN and PyrN 15 NN revealed one band. However, unlike aryl or carbonyl hydrazine, alkyl hydrazine has the limitation that it cannot be rearranged through nitrosation to produce azides …”
