4-(Trifluoromethoxy)benzaldehyde Chemical Properties,Uses,Production

Chemical Properties

clear colorless to pale yellow-green liquid

Uses

4-(Trifluoromethoxy)benzaldehyde is suitable for use in the synthesis of (E)-4-(trifluoromethoxy)benzaldehyde thiosemicarbazone. It may be used in the synthesis of:

new azo dyes containing of 5(4H)-oxazolone ring
2-[4-(trifluoromethoxy)phenyl]-1H-benzimidazole
(E)-2-[4-(trifluoromethoxy)benzylidene]indan-1-one.

General Description

4-(Trifluoromethoxy)benzaldehyde (p-(trifluoromethoxy)benzaldehyde) is an aromatic aldehyde. It participates in the synthesis of 4,5-dihydro-4-(4-trifluoromethoxyphenyl)pyrrolo[1,2-a]quinoxaline.

Synthesis

In a flask with a reflux condenser and an inlet tube, 3.62 g of 4-trifluoromethoxybromobenzene, 0.21 g of bis(triphenylphosphine)palladium dichloride, and 1.53 g of sodium formate were added with 15 ml of DMF were mixed, stirred and heated to 110 C under the condition that CO was passed. After completion of the reaction (GC), the reaction mixture was cooled to 21 C and separated from the catalyst by silica gel filtration. . The crude product obtained contained 91% p-trifluoromethoxybenzaldehyde and 7% 4-trifluoromethoxybenzyl alcohol (percentages based on area ratio in GC).
