A three-step synthesis of perfluorinated bisnoradamantane, F-tricyclo[3.3.0.03,7]octane, the smallest unsubstituted perfluorinated cage compound yet reported in the literature, is described. Oleum oxidation of adamantane to adamantane-2,6-dione followed by aerosol fluorination to F-adamantane-2,6-dione which is then photodecarbonylated in near-quantitative yields produces the perfluorinated stellane. 19F NMR spectra of these perfluorinated cage compounds, which exhibit long-range fluorine−fluorine virtual coupling, are described. The highly symmetric F-bisnoradamantane structure results in a highly symmetrical splitting pattern which is readily interpretable.

Abstract. The engineering of ubiquitous computing systems provides important challenges. Not least among these is the need to understand how to implement designs that create a required experience for users. The paper explores a particular class of such systems for built environments. In particular it is concerned with the capture of experience requirements and production of prototypes that create experience. The aim is to develop methods and tools for such environments to enable the creation of particular sorts of experience in users. An approach that combines the use of scenarios, personae and snapshots with the use of prototypes and models is described. The technique aims to elicit an understanding of the required experience of the system and then create a design that satisfies the requirements.

Aerosol direct fluorination of 1-adamantyl acetate produces F-1-adamantyl trifluoroacetate and 2-hydryl-F-1-adamantyl trifluoroacetate in a near 1:1 ratio. Hydrolyses of these two esters give the corresponding alcohols, F-adamantan-1-ol and 2-hydryl-F-adamantan-1-ol. 2-Hydryl-F-adamantan-2-ol is synthesized by LiAlH4 reduction of F-adamantanone. The acidities of these alcohols and the rates of their acetylation reactions were measured. A 1H NMR study of their hydrogen bonding with t-BuOCH3 is described.
