338800-13-8 - Reference Information
| Introduction | 2, 6-bis (di-tert-butylphosphomethyl) pyridine is an organic intermediate, 6-bis (chloromethyl)-pyridine is obtained by nucleophilic substitution with di-tert-butylphosphine. 2,6 -bis (di-tert-butylphosphomethyl) pyridine can be used to produce high quality and reproducible inorganic films on solid substrates. The film may act as a dielectric, fine-structure separator or as an electrical contact in a transistor, preferably as an electrical contact. |
| Use | di-tert-butylphosphine (1.25g,8.6 mmol) was added dropwise to 2, A suspension of 6-bis (chloromethyl)-pyridine (710 mg,4.0 mmol) in methanol (3 mL). The mixture was heated to 45 °c and stirred for 2 days. After cooling to room temperature, triethylamine (1.25mL) was added slowly and a white precipitate formed. The solvent was evaporated in vacuo and the compound 2,6 -bis (di-tert-butylphosphomethyl) pyridine was separated from the residue by column chromatography (silica, solvent: Chloroform), white solid. |
