The rates of homolytic decomposition of Cr-C(CH/sub 3/)/sub 2/OH/sup 2 +/, Cr-C(CH/sub 3/)/sub 2/CO/sub 2/H/sup 2 +/, and Cr-C(CH/sub 3/)/sub 2/CN/sup 2 +/ are 0.15 s/sup -1/, 4 s/sup -1/, and 10/sup 4/ < k < 10/sup 6/ S/sup -1/, respectively. The reaction of some aliphatic free radicals, .R with Cr/sup III/-R complexes is very fast, k/sub 3/ greater than or equal to 10/sup 8/ M/sup -1/ s/sup -1/. The rate of reaction of Cr/sup 2 +/(aq) with H/sub 2/O/sub 2/ is k/sub 16/ = (3.7 +- 0.7) x 10/sup 4/ M/sup -1/ s/sup -1/ in good accord with the literature value. These results are discussed in detail. 2 tables.
