2-bromo-2-methylbutane

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Tri n-butyl tin hydride (19.6 ml.) and α-azo-iso-butyronitrile (0.5 g.) were added succesively to a stirred solution of 2-bromo-2-methylbutane (10 g.) and acrylonitrile (43.5 ml.) in dry benzene (200 ml.). The mixture was heated at reflux for 6 hours, cooled and filtered. The residue was washed with diethyl ether (50 ml.) and the combined filtrates evaporated under reduced pressure. 4,4-Dimethylhexanenitrile was obtained as a colourless liquid (2.1 g.), b.p. 85°-94°/20 mm. The mixture was heated at reflux for 6 hours cooled filtered The residue was washed with diethyl ether (50 ml.) the combined filtrates evaporated under reduced pressure
