摘要：

The addition of •CCl3 and •But radicals to (η2-C70)Os(CO)(PPh3)2(CNBut) (1) and (η2-C70)[Os(CO)(PPh3)2(CNBut)]2 (3) was studied by ESR spectroscopy. The metal fragment in complex 1 does not influence the regioselectivity of the addition of the radicals to it. The stability of the spin adducts formed upon addition of free radicals to complexes 1 and 3 is mainly governed by delocalization of the unpaired electron over three hexagonal rings.
