N-phenylmaleimide derivatives
Abstract
Abstract NOVEL N-PHENYLMALEIMIDE DERIVATIVES PREFERABLE AS MICROBICIDES WHICH ARE REPRESENTED BY THE FORMULA 1-(2,5-DI(O=),4-R1-1,5-DIHYDRO-2H-PYRROL-1-YL),3,5-DI(X-), 4-R2-BENZENE WHEREIN R1 REPRESENTS A HYDROGEN ATOM, A HALOGEN ATOM, A LOWER ALKYL GROUP OR A PHENYL GROUP, WHICH MAY HAVE BEEN SUBSTITUTED BY A HALOGEN ATOM; R2 REPRESENTS A HYDROGEN ATOM, A LOWER ALKYL GROUP OR A HALOGEN ATOM; AND X REPRESENTS A HALOGEN ATOM, PROVIDED THAT IN CASE R1 AND R2 ARE HYDROGEN ATOMS, X REPRESENTS OTHER HALOGEN ATOM THAN A CHLORINE ATOM. EXAMPLES OF SUCH DERIVATIVES ARE: N-(3'',5''-DI-BROMO OR IODO-PHENYL) MALEIMIDES, N-(3'',4'',5''-TRIHALOGENOPHENYL) MALEIMIDES, N-(3'',5''-DIHALOGENO-4''-ALKYLPHENYL) MALEIMIDES, N-(3'',5''-DIHALOGENOPHENYL)-3-METHYLMALEIMIDES, N-(3'',5''-DIHALOGENOPHENYL)-3-PHENYLMALEIMIDES, AND N-(3'',5''-DIHALOGENOPHENYL)-3-(HALOGENOPHENYL) MALEIMIDES. THESE COMPOUNDS ARE PREPARED BY CYCLIZING CORRESPONDING MALEIC ACID MONOANILIDES UNDER DEHYDRATION CONDITIONS.
