Abstract Rate constants directly measured by GC/MS‐analyzed method for reduction of haloadamantanes by SmI 2 in presence of HMPA and H 2 O were obtained. HMPA exhibits stronger catalytic effect than H 2 O does. The result of faster reaction rate of 1‐bromoadamantane than that of 2‐bromoadamantane can be used to confirm the formation of alkyl radical as the rate limiting step of this reduction.
