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

Abstract

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
