    Notes: Abstract A recently completed study of the Scottish juvenile justice system, employing a variety of methodological approaches, is used as a source of information on the behavior and attitudes of the lay volunteers who make up “children's panels” and are responsible for decisions concerning young people who are alleged to have committed an offense or are believed to be in need of care and protection. The reported data relate to the beliefs of panel members as to the causes of delinquency and the objectives of intervention and alternative disposals; the topics they raise for discussion in children's hearings and the factors which influence the decisions they make; and the manner in which they are perceived by the children and parents who have appeared before them.

    Description / Table of Contents: α-Haloamines, XLV. The Aminomethylation of (2-Chloroethyl)hydrazines and ChloroacetohydrazidesN-(2-Chloroethyl)-N-methylhydrazine (1) reacts with dimethylmethyleneammonium chloride (2) to give the aminomethylation product 6, which can be deprotonated to the base 5. This undergoes ring closure to 1,4,4-trimethylperhydro-1,2,4-triazinium chloride (4).  -  Amino-methylation of N′,N′-dimethylchloroacetohydrazide (7) with 2 yields 8, which undergoes deprotonation to 9 and subsequent ring closure to 1,1-dimethyl-3-dimethylamino-4-oxo-imidazolidinium chloride (12). The reaction of N-methylenepiperidinium chloride with 7 is analogous to that of 2 with 7 and yields the azonia spiro compound 11.
    Notes: N-(2-Chloräthyl)-N-methylhydrazin (1) und Dimethylmethylenammoniumchlorid (2) reagieren unter Bildung des Aminomethylierungsproduktes 6; die daraus durch Deprotonierung entstehende Base 5 schließt den Ring zu 1,4,4-Trimethylperhydro-1,2,4-triazinium-chlorid (4).  -  N′,N′-Dimethylchloressigsäure-hydrazid (7) wird durch 2 zu 8 aminomethyliert, das durch Deprotonierung und Ringschluß über 9 in 1,1-Dimethyl-3-dimethylamino-4-oxo-imidazolidinium-chlorid (12) übergeführt werden kann. Analog 2 reagiert auch N - Methylenpiperidiniumchlorid unter Bildung der Azoniaspiroverbindung 11.

    Description / Table of Contents: Self-condensation of (β-Alkoxycarbonylalkylidene)ammonium SaltsIminium chlorides or trifluoroacetates of type 2, formed by protonation of β-(alkoxycarbonyl)-enamines 1, have been proved to undergo condensation to give derivatives of 4-alkyl-2-amino-6-hydroxybenzoic acid 6 via elimination of ammonium salt and alcohol. The structures of 6 had been established by spectroscopic data as well as by further reactions. The range of application of this condensation reaction has been studied and the mechanism is discussed. In the primary step presumably a nucleophilic attack on the alkoxycarbonyl group of the iminium salt 2 takes place by the enamine 1 present in the equilibrium. Analogous reactions are also found for homologues of the enamine 1 (e.g. 11, 13 and 17) to give the condensation products 12, 14, 15, and 20.
    Notes: Durch Protonierung von β-(Alkoxycarbonyl)enaminen 1 gebildete Iminiumchloride oder -trifluoracetate 2 kondensieren unter Abspaltung von Ammoniumsalz und Alkohol zu Derivaten der 4-Alkyl-2-amino-6-hydroxybenzoesäure 6, deren Strukturen spektroskopisch und durch Umsetzungen gesichert werden. Die Anwendungsbreite der Reaktion wird ermittelt und ihr Mechanismus diskutiert. Vermutlich wird primär das Iminiumsalz 2 von dem mit ihm im Gleichgewicht vorliegenden Enamin 1 nucleophil an der Alkoxycarbonylgruppe angegriffen. Analog reagieren auch homologe Enamine von 1, beispielsweise 11, 13 und 17 zu den Kondensationsprodukten 12, 14, 15 und 20.
