Supplemental Product Information:
The 100G size ships as one box with 4 x 25G bottles.
This product is designed to be stored in a freezer, as it will cause sedimentation by long-term storage.
Please shake the bottle vigorously up and down until a sediment of fine particles redisperses homogeneously before use.
If agglomerate is still remaining even after vigorous shaking, please dispose appropriately.
We recommend to consume this product as soon as possible after purchasing.

Application
TCI Practical Example: Ammonia-Free Birch Reduction Using Sodium Dispersion (SD Super Fine™)
-
Used Chemicals
-
Procedure
-
To reaction vessel under nitrogen atmosphere, 1,3-dimethyl-2-imidazolidinone (5.0 mL), tetrahydrofuran (0.42 mL) were added successively and cooled in ice bath. And SD Super Fine™ (Sodium 25wt% dispersion in mineral oil, 0.70 g) weighted in a syringe was added to the mixture. Decylbenzene (0.42 g, 1.9 mmol) and tert-butyl alcohol (0.57 g, 7.7 mmol) were added at the same temperature. After 30 minutes, confirmed consumption of raw material completely by TLC, the reaction mixture was added to ice water. The aqueous layer was extracted with hexane and the organic layer was washed with brine and dried over magnesium sulfate. After filtration, the filtrate was concentrated. The obtained crude product was purified by silica gel column chromatography (hexane) and 1-decyl-1,4-cyclohexadiene (388 mg, yield 92% (NMR), containing 13% 1-decylcyclohex-1-ene) as a colorless oil.

Experimenter’s Comments
-
The reaction mixture was monitored by TLC (hexane, Rf = 0.9).
Since this reaction does not require liquid ammonia, it is more convenient to perform than the conventional Birch reduction.
