1)  polystyrene-supported (N-phenylseleno)morpholine
聚苯乙烯负载N-硒基吗啉
1.
A novel polystyrene-supported (N-phenylseleno)morpholine was preparaed from polystyrene-supported selenium bromide and morpholine in CH2Cl2 at room temperature.
常温下,聚苯乙烯负载硒溴试剂和吗啉在二氯甲烷中反应得到新型的聚苯乙烯负载N-硒基吗啉试剂;聚苯乙烯负载N-硒基吗啉是含α-氢的醛有效的α-硒基化试剂,该负载型的α-硒基醛经卤代脱硒,以良好的产率(70%~92%)生成α-卤代醛,操作简便(过滤、洗涤),粗产物不需进一步提纯即具有好的纯度(>95%),N-硒基吗啉树脂可再生使用。
