METHOD OF PREPARING 1-(E-ALKENYL)-1-(I-BUTYL)-1-CHLORALANES Russian patent published in 2001 - IPC

Abstract RU 2161620 C2

FIELD: organic chemistry, more particularly fine organic analysis. SUBSTANCE: described is method of preparing 1-(E-alkenyl)-1-(isobutyl-1-chloralanes of general formula I: wherein R is Ph or H-C3H7,H-C4H9 by reacting diisobutylaluminium chloride (i-Bu2AlCl) with acetylene of general formula: wherein R is Ph, H-C3H7,H-C4H9, in the presence of catalyst, e.g. titanium dicyclopentadienyl chloride ((Cp2TiCl2)). Catalyst further comprises i-Bu2AlH at Cp2TiCl2 : i-bU2AlH, molar ratio of 1:(1-3), and process is carried out for 8-12 hours. EFFECT: more efficient preparation method. 1 ex, 1 tbl
