The almost exclusive products in the photochemical addition of benzophenone to methyl vinyl sulphides are the 3-methylthio-oxetanes, formed with selectivity for the trans-4-alkyl-3-methylthio configuration, as shown by an X-ray crystal structure determination and difference nuclear Overhauser effect studies.
X射线晶体结构测定和差示表明,将二苯甲酮光化学加成到甲基乙烯基硫醚中,几乎唯一的产物是3-甲硫基-氧杂环丁烷,其对反式-4-烷基-3-甲硫基构型具有选择性。核Overhauser效应研究。
