✦ Synopsis

Rate constants for the gas-phase reactions of 0 3 with a series of cycloalkenes and with cis-2-butene have been determined at 297 f 1 K. The rate constants obtained were (in units of cm3/molecule-s): cis-2-butene, 1.38 f 0.16; cyclopentene, 2.75 f 0.33; cyclohexene, 1.04 f 0.14; cycloheptene, 3.19 f 0.36; 1,3-cyclohexadiene, 19.7 f 2.8; 1,4-cyclohexadiene, 0.639 f 0.074; bicyclo]2.2.1]-2-heptene, 21.4 f 3.5; bicyclo[2.2.1]-2,5-heptadiene, 46.8 f 12.9; and bicyclo[2.2.2]-2-octene, 0.728 f 0.090. These data for cis-2-butene, cyclopentene, and cyclohexene are compared with previous literature data, and the effects of ring strain on the rate constants are discussed.
