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
afford 7-methylene-3-alkyl-3-borabicyclo[3.3.1]nonanes when treated with acetyl chloride. With the use of selectively deuterated lithium [7-D]-1,3,5-trimethyl-1-boraadamantanate, it is shown that the reaction involves the elimination of deuteride ion from the β-carbon atom.
