Abstract
Novel methods for the preparation of sodium aluminum tetraalkyls have been discovered comprising the reaction of sodium aluminum tri-isobutyl hydride and olefins. The methods avoid the use of sodium aluminum hydrides and permit in one step both the substitution of isobutyl groups and additions at hydride hydrogens to produce sodium aluminum tetraalkyls.
