1-bromo-8-methylnonane

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: By the general procedure described in Example 1 using as appropriate p-toluidine, p-anisidine, or 3- or 4-chloroaniline and isoctyl bromide, nonyl bromide or isodecylbromide (complex mixture of isomers) there were obtained:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 22.8 parts of 2,4-dihydroxyphenyl benzyl ketone, 22.1 parts of isodecyl bromide, 27.6 g. anhydrous potassium carbonate and 250 parts of dry acetone was stirred under reflux for 3 days. After cooling and filtering the filtrates were evaporated to dryness, the residue dissolved in petrol ether and the solution filtered. The filtrates well washed with 4 × 50 parts of N sodium hydroxide solution followed by 5 × 100 parts of water. The dried petrol solution was evaporated to give 26.2 parts of 2-hydroxy-4-isodecyloxyphenyl benzyl ketone as a dark, viscous oil. under reflux for 3 days After cooling filtering the filtrates were evaporated to dryness the residue dissolved in petrol ether the solution filtered The filtrates well washed with 4 × 50 parts of N sodium hydroxide solution The dried petrol solution was evaporated

Conditions: temp:20.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 40.1 parts of 2,5-dihydroxyphenyl benzyl ketone, 42.7 parts of isodecylbromide, 48.5 parts of potassium carbonate and 400 parts of dry acetone was stirred under reflux for 120 hours. On cooling to 20° C the inorganic salts were filtered off and the acetone filtrates evaporated to give a brown oil. This residue was dissolved in 200 parts of petroleum ether, filtered to remove insoluble matter, and then washed with 4 × 50 parts of N sodium hydroxide solution and finally with water. The petrol solution was dried and evaporated to yield 42.4 parts of 2-hydroxy-5-isodecyloxyphenyl benzyl ketone as a brown oil. under reflux for 120 hours were filtered off the acetone filtrates evaporated to give a brown oil filtered to remove insoluble matter washed with 4 × 50 parts of N sodium hydroxide solution and finally with water The petrol solution was dried evaporated
