Inventor: KNORR HARALD DR
IPC: C07D239/46
Filed: 1996-07-22
Abstract: Disclosed and claimed is a process for the preparation of a carbamate (IV)Ar-O-CO-NR-B(IV)by reaction of a saltM(+) (-)NR-B(II-S)with a diaryl carbonate(ArO)2CO(III).The carbamate can be reacted, without any necessity of intermediate isolation, with a sulfonamide A-SO2NH2 (V) to give a sulfonylurea (I) or salts thereofA-SO2-NH-CO-NR-B(I).And thus, disclosed and claimed too is a process for the preparation of sulfonylurea (I) by (i) contacting a salt (II-S) with a diaryl carbonate (III) to form a carbamate (IV), and (ii) contacting carbamate (IV) from step (i) with or without intermediate isolation, with a sulfonamide (V). These processes avoid the use of alkali metal hydrides as a base. And, these processes can additionally include the preparation of salt (II-S) from a compound H-NR-B (II) and base M(+)Base(-).

Abstract: L'invention concerne un dispositif de blocage de cordon qui comporte une patte extérieure (10) et une patte intérieure (11) qui sont entièrement reliées par un élément (12) formant charnière. Le dispositif est réalisé en matériau souple et élastique, de sorte que les pattes extérieure (10) et intérieure (11) se plient pour entrer en contact par coulissement l'un avec l'autre lorsqu'une pression s'applique sur leurs côtés, puis reviennent à leur position initiale, séparés l'un de l'autre, lorsque la pression est relâchée. Une ouverture (13) de la patte extérieure et une ouverture (14) de la patte intérieure sont formées dans les extrémités libres de la patte extérieure (10) et de la patte intérieure (11) respectivement. Pour bloquer le dispositif, les pattes extérieure (10) et intérieure (11) sont poussées ensemble jusqu'à ce que l'ouverture (13) de la patte extérieure et l'ouverture (14) de la patte intérieure soient alignées puis un cordon est passé dans les ouvertures. La pression de rapprochement est ensuite relâchée, ce qui a pour effet de renvoyer par coulissement les pattes extérieure (10) et intérieure (11) dans une position dans laquelle le cordon est pincé entre l'ouverture (13) de la patte extérieure et l'ouverture (14) de la patte intérieure, ce qui le bloque et l'empêche ainsi de bouger.
