| titleOfInvention | The synthesis technique of 1 (4 fluorophenyl) 2 (trans 4 alkyl-cyclohexyl) ethyl ketone |
| abstract | The invention discloses a kind of process route of new synthesis 1 (4 fluorophenyl) 2 (trans 4 alkyl-cyclohexyl) ethyl ketone, using trans (methylol) hexamethylene of 4 alkyl 1 as raw material, first with the p-methyl benzenesulfonic acid ester of the methylene of 4 alkyl alkyl of substitution sulfonic acid chloride reaction generation intermediate trans 1, potassium cyanide substituted benzenesulfonic acid root is directly added into without isolation generates trans 4 alkyl 1 (cyano methyl) hexamethylene, finally reacted with p-fluorophenyl RMgBr, again 1 (4 fluorophenyl) 2 (trans 4 alkyl-cyclohexyl) ethyl ketone is prepared through hydrolysis.The present invention has that process route is short, side reaction is few, high income, separating-purifying are easy, the low significant technology economy advantage of operating cost. |
