Definitions
- the present invention relates to a synthesis method of 9,10-bis (chloromethyl) anthracene.
- anthracene, 1,3,5-trioxane, the hexadecyltrimethylammonium bromide catalyst, hydrochloric acid and acetic acid are mixed.
- 9,10-bis (chloromethyl) anthracene is a compound used in specific recognition, molecular electronic machines, drug carriers and catalysts in organic synthesis, fluorescence optics, photodynamic therapy and optical data storage, microfabrication, precursor in the preparation of meso bi-substituted derivatives of anthracene.
- the synthetic procedure described in this document consists in passing a stream of fresh hydrogen chloride, generated in situ and continuously, to a mixture of 1,4-dioxane, anthracene, p-formaldehyde and smoking hydrochloric acid.
- the reaction crude is heated to reflux while maintaining the hydrogen chloride stream for several hours to, after interruption, continue with the system at reflux for 24 more hours.
- After abundant filtration and washing to remove impurities, the compound is finally obtained in solid form with a fairly moderate yield of 67%. As you can see, it is a very laborious experiment with a much better performance.
- 9,10-bis (chloromethyl) anthracene can be purchased from different suppliers. Sigma-Aldrich, on its website, classifies this product within a collection of 'unusual and unique chemical reagents', thus justifying its price to be quite high.
- this compound is widely used in scientific works as a structural intermediate of anthracene, which is chemically derivatized for convenience, mainly seeking the appearance of colorimetric and fluorescent optical properties.
- This compound acts as a valuable precursor in the preparation of meso-substituted derivatives of anthracene in positions 9 and 10, such as amines and their respective hydrochlorides, amides, isocyanates, alcohols, esters, ethers, thiols, nitriles, acids and phosphonates.
