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

Vinyliodide reacts chemoselectively under Heck-Mizoroki conditions with terminal alkenes, including vinylboronate esters, to give dienes. The resulting dienylboronates undergo Suzuki-Miyaura coupling with aryl, heteroaryl and alkenyl halides to access dienes...
