摘要:
The invention concerns a method for preparing an aromatic thiol bearing an amino group from a hydroxylated compound bearing an amino group. The invention also concerns the starting reagents, the intermediate products such as an aromatic S-arylthiocarbamate and the method for obtaining them and the derived products such as thioethers. The invention concerns a method for the transposition of an O-arylthiocarbamate compound bearing at least one amino group into a S-arylthiocarbamate compound bearing at least one amino group, characterised in that it consists in heating an O-arylthiocarbamate compound bearing at least one amino group and an electroattractive group. The resulting S-arylthiocarbamate compound is used as intermediate for making an aromatic thiol or thioether.

On précipite des sels contenant des ions de monomères AA-PBZ et des ions de monomères BB-PBZ à partir d'une solution aqueuse, en mettant en contact les sels solubles des monomères dans une solution aqueuse. On polymérise les sels de monomères à l'aide de techniques classiques pour former des polymères de polybenzazole sans recourir à la dévolatilisation et avec une régulation stoichiométrique très précise.

The invention relates to a new method for producing bis(3-aminophenyl)disulfides of general formula (I) and 3-aminothiols of general formula (II), wherein X and Y have the meanings specified in the description, which are used as intermediate products for the production of insecticidally, acaricidally, and nematicidally active phenyl sulfoxides.
摘要:
The present invention provides for substituted metal chelating compounds in which at least two of the chelating atoms are nitrogen which are directly attached to aromatic rings and one or more of those nitrogen atoms has attached thereto a substituent other than hydrogen, and methods for making and using these compounds. Another aspect of the invention provides for the use of the chelation compounds described above in methods for diagnostic and therapeutic purposes. A diagnostic method is described for detecting the presence or absence of a target site within a mammalian host. This method comprises providing to cells a diagnostically effective dose of a compound of the present invention which contains a metal radionuclide, such as 99mTc and/or 111In, and detecting the biodistribution of the radionuclide. A therapeutic method is described for delivering a radionuclide, such as ?186Re/188Re, 90Y, and 153¿Sm, to a target site within a mammalian host. This method comprises providing to cells a therapeutically effective dose of a chelate compound of the present invention.
