METHOD FOR PREPARING 1-ETHYL-3-ALKYL(PHENYL)-6,7- -FULLERENO[60]CYCLOHEPTA-2-OX-1-ALANES Russian patent published in 2004 - IPC

Abstract RU 2220969 C2

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to methods for preparing new organoaluminum compounds that can be used in organic and metalloorganic synthesis. Invention describes method for preparing 1-ethyl-3-alkyl(phenyl)-6,7-fullereno[60]cyclohepta-2- ox-1-alanes of the formula: wherein R is n-C3H7, n-C5H11,; Ph; n = 1-3; C60 is allotropic modification of carbon by interaction of fullerene[60] with triethylaluminium (EtAl3) excess in the presence of zirconacene dichloride (Cp2ZrCl2) as a catalyst in argon atmosphere at room temperature for 24 h in toluene medium followed by addition at temperature 15 C of cuprous chloride CuCl as a catalyst and aldehyde RCHO wherein R has above indicated values followed by stirring reaction mass in argon atmosphere at room temperature for 6-10 h. EFFECT: improved preparing method. 2 cl, 1 tbl, 1 ex
