Methods for the synthesis of the l—boraadamantane compounds, their reactions with carbonyl compounds, aromatic nitriles, nitrogenous and phosphorous ylides, as well as protolysis, halogenation, carbonylation, and amination of the 1—bora— adamantane derivatives are described. An application of l—boraadamantane to organic synthesis is considered, including the preparation of the adamantane, homoadamantane
