| titleOfInvention | Preparation of chlorinated N-methyl-imidazoles and N-methyl-imidazolines |
| abstract | In the preparation of chlorinated N-methyl-imidazoles and N-methyl-imidazolines of the formula <IMAGE> in which n represents the number 0, 1, 2 or 3 and m represents the number 0 or 1, a double bond being present between the C atoms in the 4-position and 5-position when m is 0, and a single bond being present when m is 1, by chlorinating N,N-dimethylaminoacetonitrile of the formula (CH3)2N-CH2-CN or its hydrochloride, the improvement which comprises introducing aminoacetonitrile or its hydrochloride into a mixture of its chlorination products, with simultaneous addition of chlorine gas, in the absence of a solvent, at a temperature from about 70 DEG to 150 DEG C. The product can be further chlorinated at 130 DEG to 220 DEG C. to produce tetrachloro-ethylene-bis-isocyanide dichloride. |
