YieldReaction ConditionsOperation in experiment
100% With acetic acid;aluminum nickel; In 1,4-dioxane; water; Example 19 (Reaction for Conversion from Cyano Group to Aldehyde Group) Using 82 g of dioxane, 21 g of water, 45 g of acetic acid, and 0.5 g of Raney nickel, a reaction was carried out by a method similar to Example 18. The conversion of <strong>[5216-17-1]2,3,5,6-tetrafluorobenzonitrile</strong> was found to be 100% and the yield of 2,3,5,6-tetrafluorobenzaldehyde (based on <strong>[5216-17-1]2,3,5,6-tetrafluorobenzonitrile</strong>) was 47%. The yield of 2,3,5,6-tetrafluorobenzyl alcohol was 2%.
57% With acetic acid;aluminum nickel; In methanol; water; Example 22 (Reaction for Conversion from Cyano Group to Hydroxymethyl Group) 83 g of methanol, 45 g of acetic acid, 21 g of water, 0.5 g of Raney nickel, and 5.0 g of <strong>[5216-17-1]2,3,5,6-tetrafluorobenzonitrile</strong> were added to a 500 cc stainless steel autoclave equipped with a Teflon inner tube in a nitrogen atmosphere. The gas phase was sufficiently replaced with hydrogen gas, then the autoclave was sealed and heated to 60 C. The reaction was carried out for 2 hours, Next, 1.0 g of Raney nickel catalyst was newly added, the gas sufficiently replaced with hydrogen gas, then the pressure raised to 0.5 MPa (gauge pressure). The reaction was carried out at 80 C. for 2 hours again, then the reaction solution was analyzed by gas chromatography, whereupon the conversion of <strong>[5216-17-1]2,3,5,6-tetrafluorobenzonitrile</strong> was found to be 100%, the yield of 2,3,5,6-tetrafluorobenzyl alcohol (based on <strong>[5216-17-1]2,3,5,6-tetrafluorobenzonitrile</strong>) was 57%, and the yield of 2,3,5,6-tetrafluorobenzaldehyde was 2%.
44% With sulfuric acid;aluminum nickel; In methanol; Example 16 (Reaction for Conversion from Cyano Group to Aldehyde Group) Using 158 g of methanol, 5.7 g of concentrated sulfuric acid, and 5.0 g of Raney nickel, a reaction was carried out by a method similar to Example 15. When the reaction was carried out at 25 C. for 4 hours, the conversion of <strong>[5216-17-1]2,3,5,6-tetrafluorobenzonitrile</strong> was found to be 80%, the yield of 2,3,5,6-tetrafluorobenzaldehyde (based on <strong>[5216-17-1]2,3,5,6-tetrafluorobenzonitrile</strong>) was 44%, and the yield of 2,3,5,6-tetrafluorobenzyl alcohol was 1%.
33% With sulfuric acid; acetic acid;palladium/activated carbon; Example 15 (Reaction for Conversion from Cyano Group to Aldehyde Group) 150 g of acetic acid, 50 g of 3N aqueous sulfuric acid solution, 0.875 g of 2% palladium/activated carbon, and 8.75 g of <strong>[5216-17-1]2,3,5,6-tetrafluorobenzonitrile</strong> were added to a 500 cc glass three-necked flask with a reflux condenser in a nitrogen atmosphere. The gas phase was sufficiently replaced with hydrogen gas, then a hydrogen balloon was attached to the top portion of the reflux condenser and the reaction was carried out at 80 C. for 8 hours. The reaction solution was analyzed by gas chromatography, whereupon the conversion of <strong>[5216-17-1]2,3,5,6-tetrafluorobenzonitrile</strong> was found to be 59%, the yield of 2,3,5,6-tetrafluorobenzaldehyde (based on <strong>[5216-17-1]2,3,5,6-tetrafluorobenzonitrile</strong>) was 33%, and the yield of 2,3,5,6-tetrafluorobenzyl alcohol was 7%.

YieldReaction ConditionsOperation in experiment
80% With acetic acid;aluminum nickel; In methanol; water; Example 14 (Reaction for Conversion from Cyano Group to Aldehyde Group) 0.5 g of Raney nickel, 0.31 g of a copper acetate 10 hydrate, and 50 ml of water were added to a 500 cc glass three-necked flask with a reflux condenser in a nitrogen atmosphere. The resulting mixture was stirred at 25 C. for 2 hours, then 50 ml of water and methanol were successively added and decanting performed to wash the catalyst. Further, 80 g of methanol, 100 g of acetic acid, and 5 g of water as the solvent and 8.75 g of <strong>[5216-17-1]2,3,5,6-tetrafluorobenzonitrile</strong> were newly added. The gas phase was sufficiently replaced with hydrogen gas, then a hydrogen balloon was attached to the top portion of the reflux condenser and the reaction carried out at 25 C. for 6 hours. The reaction solution was analyzed by gas chromatography, whereupon the conversion of <strong>[5216-17-1]2,3,5,6-tetrafluorobenzonitrile</strong> was found to be 100%, the yield of 2,3,5,6-tetrafluorobenzaldehyde (based on <strong>[5216-17-1]2,3,5,6-tetrafluorobenzonitrile</strong>) was 80%, and the yield of 2,3,5,6-tetrafluorobenzyl alcohol was 2%.
