Sodium Sulfate → HCID 13548392, compound

Participants

Reaction Steps

To 1 g of lithium aluminum hydride suspended in 100 ml of tetrahydrofuran and cooled to ice temperatures under dry nitrogen was added 3.86 g of the starting diketone, 1,4-bis(3,4-dimethoxyphenyl),2,3-dimethyl butane-1,4-dione, in 30 ml of dry THF. The mixture was allowed to slowly come to room temperature while stirring and finally refluxed for 1 hour and then allowed to stand overnight. One ml of saturated sodium sulfate solution was added dropwise and stirring continued for several hours. Filtration and evaporation gave a colorless oil that crystallized on addition of ether. A yield of 3.93 g (quant.) was obtained. IR spectra showed no carbonyl.
