Radical chain addition of l.l.l-trichloroetha and. respectively. l,l-dichloroethane to Ll.l.llpropellans led to bicycloCl.l.llpontane derivatives 5 and 6 which could be converted by sodium amide into the acetylenes 9 and 10. Glaser type coupling afforded the diacetylenea 12 and 13.

For the purpose of physical studies, a variety of 1,3-disubstituted bicyclo[l.l.l]pentanes (1) were required. Although there are now numerous reports of the formation of bicyclo[l.l.l]pentanes (l), few of these provide useful yields, and there appears to be no
