Reductive elimination at 1,2exo-diiodonorbornane (6) was induced by Collman's reagent. Surprisingly, 1,2endo-diiodonorbornane (9) and 1-iodo-2endo-trifluoromethylsulfonyloxy-norbornane (10b) lead only to reactions of the substituent in 2-position. Mechanistic aspects are related to the reactions of monosubstituted iodonorbornanes with Collman's reagent.
Collman试剂诱导了1,2 exo- diiodonorbornane(6)的还原消除。令人惊讶的是,1,2-内-二
