摘要: 在碱性条件下,用硼氢化钾将4-羟基-1,2-二硒杂环戊烷开环成双硒负离子,然后和二卤化物或二醇的二对甲苯磺酸酯组合关环,得到7个含羟基的二硒杂冠醚和4个含羟基的四硒杂冠醚,同时合成了2个钯配合物,并讨论了其配位特性。

关键词: 羟基, 硒杂冠醚, 钯配合物, 冠醚

Abstract: In alkaline condition,4-hydroxy-1,2-diselenacyclopentane(1)was reduced by potassium borohydride into diselenolate,then condensed with dihalides or diol ditosylate;seven diselenacrown ethers with hydroxy group(2a─8a) and four tetraselenacrown ethers with hydroxy group(2b─4b, 6b)were obtained.At the same time,the palladium compounds of crown ether 4a and 4b were prepared by reacting 4a and 4b with palladium dichloride.Their complexing characteristic was discussed.

Key words: Hydroxy group, Selenacrown ether, Palladium complex, Crown ether
