A 10 ml portion of the heptane-cyclohexane solution of magnesium 2-methyl-1-pentyloxide (6.6 mmoles) of Example I is mixed with 6.1 ml of 1.085M DBM solution in heptane. A clear solution of the 1:1 Molar complex of magnesium 2-methyl-1-pentyloxide and n-butyl-sec-butylmagnesium is obtained. Assuming total scrambling of alkyl and alkoxy groups, this complex can be represented as (n,s)-butylmagnesium 2-methylpentyloxide. The complex can also be prepared by the addition of 13.2 mmoles (1.63 ml) of neat 2-methyl-1-pentanol to 13.2 mmoles (12.2 ml) of 1.085M DBM solution in heptane.
