Preliminary mechanistic studies. a The reaction was totally suppressed when the radical scavenger 2,2,6,6-tetramethyl-piperidinyloxyl (TEMPO) was employed. b Ring-opening occurred when cyclopropane substituted styrene was used as the substrate. c When different amounts of deuterated water was added, different degrees of deuterated products were obtained
