杂元素冠醚研究（ⅪⅤ）──含羟基硒杂冠醚及其钯配合物的合成

Studies on Heteromacrocyclic Polyether(ⅪⅤ)──The Synthesis of Selenacrown Ethers with Hydroxy Group and Their Palladium Complex

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。

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.
