Treatment of ω-halo alkylamines 9 and 10 with aryl and alkyl isoselenocyanates 6a–g in the presence of triethylamine in dichloromethane gave the corresponding 1,3-selenazolidines 11a–g and perhydro-1,3-selenazines 12a–g, respectively, in good to excellent yields. Chemical and spectroscopic evidence for the structures of all new compounds are presented, and in selected examples the molecular structures
在二氯甲烷中,在三乙胺存在下,用芳基和烷基异硒氰酸酯 6a-g 处理 ω-卤代烷基胺 9 和 10,分别得到相应的 1,3-硒唑烷 11a-g 和全氢-1,3-硒嗪 12a-g。良好的产量。介绍了所有新化合物结构的化学和光谱证据,在选定的例子中,分子结构已通过 X 射线晶体学确定。与异硫氰酸酯的类似反应已用于制备 1,3-噻唑烷和全氢-1,3-噻嗪。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
