ABSTRACT:
Novel organoaluminum compounds having the formula XYA1 ##STR1## in which X is a halogen, Y is an alkyl group having from 1 to 10 carbon atoms, a phenyl group or a halogen, R is an alkyl group having from 2 to 9 carbon atoms, and n is an integer from 1 to 20. These compounds are less viscous and more soluble in hydrocarbon solvents than are corresponding ethylene-based or butadiene-based compounds. The novel compounds are prepared by the reaction of alkylaluminum dihalides or aluminum trihalides with a terminal olefin having from 3 to 10 carbon atoms in the presence of aluminum metal.
