Synthetic transformations of the 1-bicyclo[1.1.1]pentyl bridgehead radicals 11 generated from the corresponding bridgehead iodides 3 and carboxylic acids 5 are described. The relatively high nucleophilicity of these radicals was utilized in reactions with carbonyl compounds. In the reaction sequence of preparation of the iodides 3 and their further transformations, [1.1.1]propellane (2) is a synthetic equivalent of the recently described bicyclo[1.1.1]penta-1,3-dienyl dianion (8).

The IR spectra of the rust five oligomers of [1.1.1]propellane ([n]staffanes, n = 1-5), and some of their bridgehead-deuteriated derivatives, have been measured in argon matrix isolation. IR transition moment directions were obtained using stretched polyethylene as solvent. Assignments were based on a simple model of interacting subunits and on comparison with 3-21G HF calculations. IR peaks particularly suitable for use in the determination of orientation of the staffane moieties in supramolecular assemblies have been identified.
