Combined with our previous relative rate measurements (Int. J. Chem. Kinet., 24, 803 (1992)), the rate constants obtained relative to k(O-3 + propene) = 1.00 were: 3-penten-2-one, 3.62 +/- 0.16; 2-cyclohexen-1-one, <0.19; bicyclo2.2.2-2-octene, 7.44 +/- 0.48; 1,3-cycloheptadiene, 16.1 +/- 1.1; cycloheptene, 23.7 +/- 1.6; 1,3-cyclohexadiene, 134 +/- 13; bicyclo2.2.1-2-heptene, 170 +/- 16; and bicyclo2.2.1-2,5-heptadiene, 390 +/- 36. The resulting rate constants then lead to a self-consistent set of room temperature data for the reactions of O-3 with these alkenes and alpha, beta-unsaturated ketones. These rate constants are compared with the literature data, and the effects of ring size discussed. (C) 1994 John Wiley & Sons, Inc.
