The syntheses of isomeric diadamantylphosphinic acid chlorides are reported. By high-field two-dimensional NMRspectroscopy all proton and carbon-13 signals were identified and assigned unequivocally. Diastereotopism effects and the conformational behaviour of these compounds are discussed.

A convenient method for dichlorophosphorylation of adamantanols and 1-adamantyl alcohols with phosphorus trichloride in trifluoroacetic acid is described. The dichlorophosphoryl group is selectively introduced to the different positions of the adamantane nucleus as well as to the α-position of the side chain. The dichlorophosphorylation of 1-adamantylmethanol is found to be accompanied by adamantane-homoadamantane rearrangement leading to 3-homoadamantylphosphonic dichloride in 70% yield.
