The free radical addition reactions of [1.1.1] propellane (1) are described in some detail and allowed the preparation of a wide variety of 1,3-disubstituted bicyclo [1.1.1.] pentanes. The reaction of 1 with free radicals was more rapid than that of bicyclo [1.1.0] butane (2), whereas bicyclo [2.1.0] pentane (3) was relatively inert

A convenient method for acylation of [1.1.1]propellane to give bicyclo[1.1.1]pentane (BCP) carboxamides and ketones has been developed. It provides a straightforward one-step access to monosubstituted BCP carboxamides, synthesis of which requires multiple chemical steps in previous reports.
