Yield:37909-95-8 98%

Reaction Conditions:

with Rh/Al2O3;hydrogen;tin(IV) chloride in methanol at 20; under 75007.5 Torr; for 2 h;Autoclave;

Steps:

3 Example 3

Put 4-butyrylbiphenyl (1mol, 224.2g), rhodium/alumina (with rhodium mass 5g), tin tetrachloride (0.2mol, 52.1g) into the autoclave, add 500 mL of methanol, and react to the high pressure The kettle was replaced with nitrogen for three times and then with hydrogen for three times, then filled with hydrogen (10MPa), stirred and heated at 20°C, reacted for 2h, after the reaction, the reaction solution was filtered, the filter residue was washed twice with a small amount of ethanol, and the filtrate After being combined with the washing liquid, the solvent was recovered by distillation under reduced pressure to obtain 4-butylbiphenyl with a content of 99% and a yield of 98%.
