Claims11
An acylpyrazine ether corresponding to the formula:
- ##STR19## where R is a substituent selected from aliphatic, alicyclic and aromatic hydrocarbyl groups having 2-12 carbon atoms, R.sup.1 is a substituent selected from hydrogen and alkyl groups having 1-6 carbon atoms, X is etheric oxygen or sulfur, and R.sup.2 is a substituent selected from aliphatic, alicyclic and aromatic hydrocarbyl groups having 1-12 carbon atoms, with the proviso that the position-(3) substituent is not hydrogen.
1-(3-Ethylthio-2-pyrazinyl)-1-propanone.
1-(3-Methoxy-2-pyrazinyl)-2-methyl-1-propanone.
1-(3-Furfurylthio-2-pyrazinyl)-2-methyl-1-propanone.
1-[3,6-Dimethyl-5-(cis-hex-3-enoxy)-2-pyrazinyl]-1-propanone.
A halo-acylpyrazine corresponding to the formula:
- ##STR20## where Y is a halogen atom, R is a substituent selected from aliphatic, alicyclic and aromatic hydrocarbyl groups having 2-12 carbon atoms, and R.sup.1 is a substituent selected from hydrogen and alkyl groups having 1-6 carbon atoms, with the proviso that the position-(2) substituent is not hydrogen.
1-(3-Chloro-2-pyrazinyl)-1-propanone.
1-(3-Chloro-2-pyrazinyl)-2-methyl-1-propanone.
1-(5-Chloro-3,6-dimethyl-2-pyrazinyl)-1-propanone.
A halo-acylpyrazine corresponding to the formula:
- ##STR21## where Y is a chlorine atom, R is a substituent selected from aliphatic, alicylclic and aromatic hydrocarbyl groups having 2-12 carbon atoms, and R.sup.1 is a substituent selected from hydrogen and alkyl groups having 1-6 carbon atoms, with the proviso that the position-(2) substituent is not hydrogen.
A halo-acylpyrazine corresponding to the formula:
- ##STR22## where Y is a bromine atom, R is a substituent selected from aliphatic, alicylclic and aromatic hydrocarbyl groups having 2-12 carbon atoms, and R.sup.1 is a substituent selected from hydrogen and alkyl groups having 1-6 carbon atoms, with the proviso that the position-(2) substituent is not hydrogen.
