Electrophilic Routes to Tertiary Adamantyl and Diamantyl Phosphonium Salts

[摘要]：In highly nonpolar media both 1-adamantyl and 1-diamantyl triflates are sufficiently stable to react with nucleophiles in a controlled manner. Several tertiary phosphonium triflate salts with a single adamantyl or diamantyl residue were prepared directly in this way, starting with the secondary phosphine. Three compounds with the 1-phosphodiamantane structure were characterised by X-ray.
