F. Tittelbach et al., AMINOLYSIS OF 2,5-BIS(ARYLOXY)-3,3A-LAMBD A-4,4-TRITHIA-1,6-DIAZAPENTALENES - AN ENTRY TO MACROCYCLIC HETEROPENTALENES, Chemische Berichte, 127(11), 1994, pp. 2209-2213
The 3,3alambda4,4-trithia-1,6-diazapentalenyl)diamines 6, 7 and azacro
wn ethers 8, incorporating two sulfur-containing diazapentalenes, have
been synthesized from (aryloxy)-3,3alambda4,4-trithia-1,6-dizapentale
nes 1 and diamines. The aminolysis of 1 with amines has also been stud
ied providing 2-monoamino- 3 and 2,5-diaminoheteropentalenes 4.
