Attack of a free-radical on norbornene or norbornadiene is generally thought to occur from the 8x0 side (1,2), although exceptions have been reported (3). There are many examples of exo-addition to norbornene by freeradicals (11, but few studies have been made on the sterochemistry of freeradical ad
