The Willgerodt–Kindler reaction of 1-(1-adamantyl)propan-2-one and its derivatives was studied by gas chromatography–mass spectrometry. The reaction time was found to be 3–4 times longer than in the case of alkyl aryl ketones due to considerable steric hindrances in the molecules of adamantyl ketones. The use of diglyme as solvent and sodium butyl xanthate as catalyst significantly shortened the reaction time and improved the yield to 92%. 相似文献

Ionization constants of {(2-amino)-bicyclo[2.2.1]-hept-3-yl}anilines and {(2-aminomethyl)bicyclo [2.2.1]-hept-3-yl}anilines in nitromethane have been determined by potentiometric titration. Due to high values of pK a 1 BH+ and pK a 2 BH+ (close to known adamantane-containing diamines) the studied compounds are promising candidates for preparation of (co)polyimides with a complex of excellent utilitarian properties. 相似文献

On the basis of [(2-amino)- and (2-aminomethyl)bicyclo[2.2.2]hept-3-yl]anilines, new soluble polyimides and copolyimides are synthesized. They are characterized by high thermal stability and increased hydrolytic stability that significantly surpass those of aromatic polyimides. 相似文献
