Ethane → N-diethylboranyl-2-methylpropan-2-amine

Participants

Reaction Steps

A mixture of 14.6 g. (0.2 moles) of t-butylamine and about 30 g. (0.3 moles) of triethyl borane after addition of about 1 g. of diethyl boryl pivalate is heated to 60° to 80° C. with stirring. Within 2.5 hours, 6.2 normal liters (92%) of ethane are evolved. Distillation under vacuum gives 24 g. (85%) of pure t-butylamino-diethyl borane boiling at 45° C./18 mm. Hg after having collected unconsumed triethyl borane. The residue weighs about 1 g.
