A mixture is prepared from 18.4 g. (0.1 moles) of triisobutylborane and 0.5 g. pivalic acid and heated to 70° C. Within 3 hours, 9.4 g. (0.1 moles) of aniline are added dropwise and then heating is continued for 2.5 hours to a maximum of 80° C. 1890 Nl (84.4 Mmoles) of isobutane are evolved. After having collected a small amount of first runnings of b.p. up to 28° C./0.1 mm. Hg, 18.4 g. (84.8%) of colorlos anilinodi-isobutyl borane of b.p. 49°-51° C./0.1 mm. Hg and 1.1 g. of residue are obtained.
