摘要

Multicyclic cagelike cyclo-phanes 2a and 2b containing cyclobu-tene rings have been prepared as precursors of three-dimensional polyynes C_(78)H_(18) (la) and C_(78)H_(12)C1_6 (1b),respectively.Laser irradiation of 2 a and 2b induced expulsion of the aromatic fragment,indane,to give the three-dimensional polyyne anions C78H_(18)~- and C_(78)H_(12)C1_6~-,respectively. Whereas the former anion lost only four hydrogen atoms to form C_(78)H_(14) ,complete loss of all hydrogen and chlorine atoms was observed from the latter anion,to yield a C_(78)~- ion that has a fullerene structure which was proven by its characteristic fragmentation pattern.
