摘要:
R.sup.2 represents an optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, aralkyl or aryl radical, andR.sup.3 represents an optionally substituted alkyl, aralkyl, aryl or heteroaryl radical,and salts thereof, with the exception of the compounds:2-(2-methoxycarbonyl-phenylsulphonylaminocarbonyl)-4-methyl-5-methoxy-2,4-dihydro-3H-1,2,4-triazol-3-one,2-(2-trifluoromethoxy-phenylsulphonylaminocarbonyl)-4-cyclopropnl-5-methoxy-2,4-dihydro-3H-1,2,4-triazol-3-one,2-(2-difluoromethoxy-phenylsulphonylaminocarbonyl)-cyclobutyl-5-ethoxy-2,4-dihydro-3H-1,2,4-triazol-3-one, and2-(2-methoxycarbonyl-phenylsulphonylaminocarbonyl)-4-ethyl-5-ethoxy-2,4-dihydro-3H-1,2,4-triazol-3-one.

The invention relates to new sulphonylaminocarbonyltriazolinones of the formula (I) ##STR1## in which Q represents oxygen, sulphur or one of the following groups ##STR2## (in which the radicals R.sup.1, R.sup.2, R.sup.3 and R.sup.4 have the meanings given in the description),as well as to salts of compounds of the formula (I), to processes and novel intermediates for the preparation of the novel compounds, and to their use as herbicides.
摘要:
Alkoxytriazolinones of the general formula (I), ##STR1## in which R.sup.1 and R.sup.2 independently of one another represent in each case optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkylalkyl, aryl or arylalkyl,(which can be used as intermediates for the preparation of herbicidal active compounds) are obtained in very good yields and in high purity by reacting iminothiocarbonic diester (II) with carbazinic esters (III) ##STR2## in which R.sup.3 and R.sup.4 in each case represent, for example, alkyl or aryl, at -20.degree. C. to +50.degree. C. (1st step) and subjecting the semicarbazide derivatives (IV) formed in this process with elimination of R.sup.3 -SH ##STR3## to a cyclizing condensation reaction and if appropriate in the presence of a base at 20.degree. C. to 100.degree. C. with elimination of R.sup.4 --OH, if appropriate after intermediate isolation (2nd step).

摘要:
This invention relates to novel polycarbonates having hydroxyl end groups and an average molecular weight of 500 to 12,000, as determined by measuring the OH number, and being based on dimer diols containing either 36 or 44 carbon atoms. These novel polycarbonates are particularly suitable for the use in a process for the production of polyurethane plastics which are stable to hydrolysis and oxidation.
