| titleOfInvention | Process for the preparation of alkoxytriazolinones |
| abstract | Alkoxytriazolinones of the formula (I), in which R1 and R2 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 good yields and in high purity by reacting iminocarbonic diesters (II) with carbazinic esters (III) in which R2 and R3 in each case represent, for example, alkyl or aryl, at -20°C to + 120°C (1st step) and subjecting the semicarbazide derivatives (IV) formed in this process with elimination of R2-OH to a cyclizing condensation reaction in the presence of a base at 20°C to 150°C with elimination of R3-OH, if appropriate (2nd step) and, finally, by reacting the resulting 5-alkoxytriazolinones of the formula (V)[=formula (I) where R1 = H] with an alkylating agent of the formula R1-X(VI)[X, for example, = halogen or -OSO2OR1] at 0°C to 150°C, if appropriate in the presence of a base (3rd step: highly selective 4-alkylation). |
