Our main purpose is to draw attention to the relative stability of three-electron ?-bonded radicals (?12, ?21), the large number of such radicals that have been studied by EPR spectroscopists, and their potential importance as reaction intermediates.The topic is illustrated by experiments which show that when R3P.+ radical cations (Me3P.+ amd Ph3P.+) are generated in CFCl3 at 77 K by exposure to 60Co γ-rays, and the system is annealed to ca. 155 K, features characteristic of R3PCl radicals are detected, with well defined hyperfine coupling to 31P and 35/37Cl nuclei.It is argued that these must have been formed from chloride ions released from (CFCl3).- radical-anions following electron capture.
