The reaction between singlet oxygen and cis- and trans-2-butene-1,1,1-d 3 has been studied. The product isotope effects (k H /k D ) were found to be 1.38 and 1.25, respectively. Similarly, N-phenyl-1,2,4-triazoline-3,5-dione (PTAD) reacts readily with these substrates and shows isotope effects that are larger (5.36, 1.29) but in the same direction. 2-Methyl-1-propene-3,3,3-d 3 is unreactive with singlet
已经研究了单线态氧与顺-和反-2-丁烯-1,1,1-d 3 之间的反应。发现产物同位素效应 (k H /k D ) 分别为 1.38 和 1.25。类似地,N-苯基-1,2,4-三唑啉-3,5-二酮 (PTAD) 很容易与这些底物反应,并显示出更大 (5.36, 1.29) 但方向相同的同位素效应。2-Methyl-1-propene-3,3,3-d 3 与单线态氧不反应,但很容易与 PTAD 反应,产物同位素效应为 1.25
