✦ Synopsis

Hexafluoro acetone CF 3 COCF 3 has been shown to react rapidly with the CH 2 OO, CH 3 CHOO, and (CH 3 ) 2 COO intermediates that are formed in the ozonolysis of C 2 H 4 , trans-2-C 4 H 8 , and 2,3-dimethyl-2-butene, respectively, and to form products tentatively assigned to the corresponding secondary ozonides. Relative rate method applied to the C 2 H 4 ozonolysis has indicated that CF 3 COCF 3 reacts ϳ13 times faster than CH 3 CHO.
