opanoate, 6, to give the corresponding sulfonium salt peresters 2a-c, and 3 in good yield. Laser flash photolysis of these compounds affords the known two-sulfur, three-electron stabilized cation radicals 2a, b, and 5 which were characterized by optical absorption spectroscopy.
所选的二烷基二硫醚1,5-二硫代蔗糖,1,4-二硫代庚烷,1,4-二硫杂环庚烷和2,6-二硫杂庚烷很容易在硝基甲烷中被O-三氟甲磺酰基-3-羟基过氧丙酸叔丁基酯6烷基化,得到相应的sulf盐过酸酯2a-c和3均具有良好的收率。这些化合物的激光快速光解得到已知的二硫,三电子稳定的阳离子自由基2a,b和5,其通过光吸收光谱法表征。
