摘要

Diazahexathia-24-crown-8 ( 2) has been isolated from the reaction mixture during the preparation of monoazatrithia-12-crown- 4 ( 1). When N-Boc protectedbis(2-chloroethyl)amine was employed as a starting material, N-Boc protected monoazatrithia-12-crown- 4 ( 3) and N-Boc protected diazahexathia-24-crown-4 ( 4) were separated easily. Double-armed diazahexathia-24-crown-8 having two 3',5'-dichlorobenzyl groups (5a) or two 2-phenylethyl groups (5b) were also prepared using reductive amination. The stoichiometry and detailed structures of the Ag+ complexes with 5a and 5b were investigated by H-1 NMR titration experiments and X-ray crystallography.
