Synthesis of ?-sulfur-containing 2-imidazolinone derivatives

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1973
1. A method was developed for the synthesis ofα-sulfur-containing derivatives of 2-imidazolinone by the reaction of 4(5)-piperidino-methyl-2-imidazolinones with mercaptans, carbon disulfide and thioacetic acid. 2. 4(5)-Methyl-5(4)-S-acetylmercaptomethyl-2-imidazolinone was converted to bis[4(5)-methyl-2-imidazolinonyl-5(4)-methyl ...

Synthesis of 4(5)-alkyl-2-imidazolinones

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1986
1. A mixture of 1- and 3-bromo-2-alkanones reacts selectively with piperidine in benzene or trimethylamine in aqueous ethanol to form the corresponding 1-piperidino-2-alkanones of (β-oxoalkyl)trimethylammonium bromides. 2. Cyclocondensation of 1-piperidino-2-alkanones and (β-oxoalkyl)trimethylammonium bromides with urea leads to 4(5 ...

Imidazolinon i sulfonilureja herbicidi

1991
Prikazane su fizikalno-kemijske i biološke karakteristike dviju relativno novih skupina herbicida: imidazolinona i sulfonilureje. Detaljno je prikazana povijest, sinteza, mehanizmi djelovanja, spektar djelovanja na korove, mehanizmi selektivnog učinka na kulture, stanje i registracija pojedinih predstavnika skupine u Hrvatskoj.

Structure‐activity relationships among the imidazolinone herbicides

Pesticide Science, 1990
AbstractThe structure of the imidazolinone herbicides consists of three distinct moieties: the imidazolinone ring, the carboxylic acid and the backbone. The effect of changes in each of these on herbicidal activity, crop selectivity and AHAS enzyme inhibition has been studied.

Mogućnost upotrebe imidazolinon herbicida u kukuruzu

2000
Korovi u svakom usjevu, pa tako i kukuruzu, mogu nanijeti značajne štete stoga ih valja pravovremeno i što učinkovitije suzbiti. Ostojić i sur. (1996) navode da u kukuruzu, procjenom ukupnih šteta nastalih napadom štetočinjaca, na štete od korova otpada 8%. Pri suzbijanju korova primjenom herbicida mogu se javiti određeni problemi.
