Prganic Nitrosonium Salts as Oxidants in Organic Chemistry

Abstract

Order-and Psychologists-in the Court This is not like squeezing the grapefruit one more time for that last bit of juice. It is more like remembering that there is the other half still untouched.Last September this column made a foray into the courtroom, did a bit of reconnoitering with the help of psychologists who knew the terrain, promptly took cover again to study the field maps. With the help of our colleagues who had lived among the natives, we interpreted the language of the land of law, looked a bit at its culture, and found the setting if not unsettling at least awfully awesome.The subject seems to appeal to our readers, who continue to express interest, report experiences, and, all in all, remind us that forensic psychology is here to stay. We turn, then, to that other half of the questionnaire which was being pretested on a group of some 40 colleagues describing some 80 professional brushes with the law (with a range of from 1 to 10 cases, a mode between 1 and 2). And here are some of the things we find.Where Did You Go? Court. What Did You Do? Testijy. The author of the best seller will pardon us if we adapt his apt title. It captures so well the spirit of our situation. For apparently psychologists go to all kinds of courts to testify in all types of cases on all sorts of issues.The list of courts in which our respondents have appeared covers the legal waterfront: federal, state, district, circuit, county, municipal. There is the superior court, the state supreme court, and the more restful sounding supreme bench. There are probate courts, domestic relations courts, and juvenile courts. And, if one wants more exotic places where psychologists have been, there is the County Assizes of the Supreme Court of Canada as well as Queen's Bench Court.The actions involved, as one might suspect, are hardly all of a piece. We referred to some of the more grisly in the earlier column. We add here only that, no matter what the case may be, from traffic fine to felony, whichever side tries most to win it, psychologists may well be in it.In the returns, cases in criminal law outweigh

Search for Unified Action Mechanism of Hindered Amine Light Stabilizers

“…For example, a reaction like Hoffman decomposition takes place under the action of a base to produce a nitroso compound, if a double bond with oxygen or nitrogen is present at the 4-position of the piperidine ring 31),34), 37) . If a nitrosonium has chloride ion as the counter anion, ring cleavage also occurs under the action of sodium benzoate and silver benzoate, even if the 4-position has no double bond 33) .…”

Selectfluor: Mechanistic Insight and Applications

“…[83] However, the fact that 2,2,6,6-tetramethylpiperidine N-oxide (TEMPO), which is oxidized by a suitable oxidant (Cl 2 , Br 2 , XeF 2 , etc.) by liberation of a single electron, [84] reacts rapidly with selectfluor [20] strongly suggests that selectfluor can participate in SET reactions. Based on this evidence and on additional data supporting SET with other NÀF reagents, it is probable that SET also occurs with selectfluor, but that the radical intermediates are strongly destabilized and therefore unlikely to be detected.…”

Electrocatalytic Oxidation of Carbohydrates Mediated by Nitroxyl Radical‐modified Electrodes in Aqueous Solution

“…Organic nitroxyl radicals are known to be an effective redox mediator for various types of oxidation reactions with organic compounds [3]. A number of groups have recently reported the development of efficient organic nitroxyl radical catalyzed reactions [4][5][6][7].…”
