摘要：

The rate constant for ring opening of the 1-(trans-2-phenylcyclopropyl) ethen-1-yl radical, 4, generated by photolysis of the corresponding vinyl iodide 2, is reported. The value of the rate constant was determined by the tin hydride method and was found to be (1.6 +/- 0.2) x 10(10) s(-1), one order of magnitude smaller than the rate constant for rearrangement of the trans-2-phenylcyclopropylcarbinyl radical.
