METHOD OF PREPARING 1-CHLORO-TRANS-3,4-DIALKYL SUBSTITUTED INDIUM CYCLOPENTANES Russian patent published in 2001 - IPC

Abstract RU 2164227 C2

FIELD: organic chemistry, more particularly catalytic system components, processes of oligomerization and polymerization of unsaturated compounds, fine organic and organometal synthesis. SUBSTANCE: method comprises reacting alpha-olefins R, wherein R is H.-C4H9, H.-C5H11, H.-C6H13 with metallic magnesium and indium trichloride in molar ratio of (20-22):(10-14) respectively in the presence of two-component catalyst composed of zirconacene dichloride (Cp2ZrCl2) in amount of 2-5 mole % with respect to magnesium and diisobutyl aluminium hydride (i-Bu2AlH) in Cp22rCl2:i-Bu2AlH molar ratio of 1: (1-3) in argon atmosphere under normal conditions in tetrahydrofuran solvent. Yield of the desired products is 60-82%. Method makes it possible to prepare new organoindium compounds with high regioselectivity. EFFECT: more efficient preparation method. 1 ex, 1 tbl
