General description

1,3-Dimethyladamantane undergoes C-H insertion reaction with phenylchlorocarbene. It reacts with with molecular oxygen in the presence of N-hydroxyphthalimide combined with cobalt salts to yield 3,5-dimethyladamantan-1-ol and 5,7-dimethyladamantane-1,3-diol.

Application

1,3-Dimethyladamantane was used in the synthesis of 1,3-dibromo-5,7-dimethyladamantane.
