✦ Synopsis

1~ has recently been shown tbal the parent. cycbc struclure for the qclopropane radical cation undergo ring opening in a CFCi,CF,Cl matrix However, the ESR results show tiat the derived species has a SOMO loc~bsed on only one of the terminal CH, groups. This apparently requires a Limiting orthogonal structure for rhe outer CH, groups rendenng one similar to a normal alkyl radical and fhe other to a normal carbocation-Since C-H h~e~nju~tion for the -CH: unit is m.iniW by the structure detected. it till be an extremely powerful ekctrophk It is lherefore suggested that bonding IO one chlorine ligand of a solvent molecule occurs However. if this is tie species studied by ESR spectroscopy. there is no need to postulate
