The structure of propellane (bond lenghts and angles) was determined from an analysis of the rotational components of the infrared bands of the parent compound and of its d6 derivative, and it was found to be in good agreement with the structure ca

The pKa's of eight 3-substituted bicyclopentanecarboxylic acids have been measured and found to correlate well with ?I constants.The value of ρI (2.23 +/- 0.12) is large but not large enough to propose any special perturbation of normal field-inductive effects by the close proximity (about 1.88 Ae) of the bridgehead carbons.Also determined were the products and rates of solvolyses of the p-nitrobenzoates of three 3-substituted 1-pentanes.The products were primarily unrearranged, and the rates again showed no surprisingsubstituent effects.A practical synthesis of 1,3-disubstituted bicyclopentanes has been developed and is described.
