New azacrown and azathiacrown ethers (5a-c and 7), incorporating two thiourea moieties, were synthesized from the hypervalent sulfur-containing tetraazapentalene (1) and diisothiocyanate derivatives of oligoethylene glycols and from 1 and 3,6,9-trithia-1,11-undecanediisothiocyanate, respectively, by cyclization and then desulfurization.
由高价含硫的四氮杂戊烯(1)和低聚乙二醇的二异硫氰酸酯衍生物以及1和3,6,9-trithia-1(1,3,6,9-trithia-1 )合成了新的氮杂双氮杂和氮杂双氮杂氮杂醚(5a-c和7),其中包含两个硫脲部分。 11-十一烷二异硫氰酸酯分别通过环化然后脱硫。
