  • Conversions of hydrazones to diazo compounds by n-butyllithium and azidotris(diethylamino)phosphonium bromide
    作者:Mark McGuiness、Harold Shechter
    DOI:10.1016/s0040-4039(02)01443-0
    日期:2002.11
    Lithium hydrazonides, prepared by reactions of hydrazones with n-BuLi/hexane in THF at −78°C, are converted by azidotris(diethylamino)phosphonium bromide in THF at ∼0°C efficiently, rapidly, and safely to their corresponding diazo compounds along with tris(diethylamino)phosphorimine, nitrogen, and lithium bromide.

  • Studies of thermal rearrangements of methyl 3-alkyl-3-methyl-3H-pyrazole-5-carboxylates. Concerted, stepwise, and unclassified mechanisms
    作者:Elizabeth A. Jefferson、John Warkentin
    DOI:10.1021/jo00081a028
    日期:1994.1
    Studies of the thermal rearrangements of five 3H-pyrazoles are described, in which the migrating groups were methoxymethyl, tert-butyl, 1-adamantyl, p-methoxybenzyl, and benzyl. On the basis of reaction products, rearrangement of the (methoxymethyl)pyrazole in benzene, dichloromethane, and methanol at room temperature occurs by a stepwise mechanism, involving discrete ion-pair intermediates. Observed first-order rate constants, for the rearrangement of four of the 3H-pyrazoles in benzene-d(6) and acetone-d(6) at higher temperatures, were determined The tert-butyl compound also rearranges by a stepwise mechanism in benzene d(6), acetone-d(6), and methanol-d(4) based on the fact that isobutene and tert-butyl methyl ether (in methanol) are coproducts of rearrangement. The mechanism of rearrangement of the adamantyl and methoxybenzyl systems, in both benzene d(6) and acetone-d(6) solvents, is ambiguous, the distinction between stepwise, with tight ion-pair intermediates, and concerted, with some charge separation, being unclear. However, both afforded a methyl ether in low yield during rearrangement in methanol solvent, which suggests a stepwise, ion-pair mechanism for rearrangement in that medium. No methanolysis product could be detected from the rearrangement of the benzyl compound in methanol, which suggests concerted rearrangement. Additional evidence that it rearranges by a concerted mechanism is the fact that it affords only one pyrazole product, whereas the others afford two or more.
  • Advantageous Syntheses of Diazo Compounds by Oxidation of Hydrazones with Lead Tetraacetate in Basic Environments
    作者:Terrence L. Holton、Harold Schechter
    DOI:10.1021/jo00120a013
    日期:1995.7
    Varied sensitive diazo compounds 3 are produced efficiently and safely in 3-6 g quantities by oxidation (eq 1) of hydrazones 1 at -78 degrees C with lead tetraacetate (2) in triethylamine/chloroform, N-methylmorpholine/dimethylformamide, tetramethylguanidine (8)/dimethylformamide, and tetramethylguanidine/methylene chloride, respectively, upon use of appropriate workup and handling techniques. New and improved nonhazardous procedures have been developed for preparing and handling hydrazones 1 from aldehydes and ketones in reactions with excess hydrazine.
