- Product Name:DYSPROSIUMCHLORIDE
- CAS Number:10075-74-8
- Molecular formula:C12H12S2
- Molecular Weight:220.35
Yield:10075-74-8 79%
Reaction Conditions:
with potassium carbonate in acetone at 20;Inert atmosphere;
Steps:
1
The synthesis of the compound (e) was next conducted with reference to Scheme 3 in Toyoshi Shimada, et al., “Nickel-Catalyzed Asymmetric Grignard Cross-Coupling of Dinaphthothiophene Giving Axially Chiral 1,1′-Binaphthyls,” J. Org. Chem. J. Am. Chem. Soc., 2002, 124, 13396-13397. Described specifically, under an argon (Ar) atmosphere in a 4-necked flask, 1,5-dimethylcaptonaphthalene, potassium carbonate and methyl iodide were stirred overnight at room temperature in acetone. Here, the chemical equivalents of 1,5-dimethylcaptonaphthalene, potassium carbonate and methyl iodide were “1,” “6” and “2,” respectively. Distilled water (500 milliliter (mL)) was then added to the reaction suspension, and the precipitated solid was collected by filtration, followed by purification. As a result, the compound (e) was obtained as a pale yellow solid with a yield of approximately 79%.
