Charge transfer complexes of some N‐methylated thiohydantoins with molecular iodine

Abstract

Using a series o f N-methylated thiohydantoins as sub

UV‐visible, IR, and 13C NMR studies on CT complexes between some thiohydantoins and molecular diiodine

“…In this article, we will report the results of the determination of the K's and the thermodynamic parameters of Reaction 1 for compounds 1, 2 , and 4 and compare them with the results obtained for compounds 3, 5 , 6 , 7 , and 8 reported in a previous article [6].…”

“…3,5,5-trimethyl-4-oxoimidazolidine-2-thione (9, 3,5,5-trimethylimidazolidine-2,4-dithione (6), 5,sdimethyl-4-oxoimidazolidine-2-thione (7), and 5 5 dimethylimidazolidine-2,4-dithione (8) have been prepared according to the literature [6,8,9,101. Diiodine was purified by sublimation from KI and stored in a desiccator.…”

“…mol-' . K-') of the 1 : 1 Adducts between Molecular Diiodine and 1-8 Ks of this compound have been redetermined, since they do not fit the other values depicted inTable 5, being clearly underestimated[6].…”

Halide-bridged polymers of divalent metals with donor ligands – structures and properties

“…Structurally characterized derivatives of divalent metals which feature coordination of additional donor ligands are restricted to Hg(II) [19][20][21][22][23][24][25][26] with its general preference towards lower coordination numbers and to Zn(II) [27,28], a rather small divalent cation. Fig.…”
