“…These isotope shifts, Ay(13C), observed as displacements of the doublet centrums from the 13C signal of cyclohexane-iV, are equal to 2.70 and 0.64 Hz for the doublets spaced 3.81 and 5.06 Hz, respectively, which favor the following assignment: Vv = 3.81 Hz, and 3/av = 5.06 Hz. 6 At low temperatures (-104 °C in our experiments) the ring r(C-Ha) = 1.101 andr(C-He) = 1.141 Á. Other geometric parameters as in ref 14.…”

“…For the 2 : 1 [COL]~+-O, adduct with L5, equation (5) derived from (3) gave the best fit with the pH titration data. The definitions of the terms in this equation and its derivation were described in our previous papers.…”

The protonation and complex formation of macrocyclic polyamines containing a sulphur donor atom, 1 -thia-4,7,1O-triazacyclododecane ( L4) and 1 -thia-4,7,11,14-tetra-azacyclohexadecane ( L5), have been investigated with the metal ions Co", Ni", Cu1[, Hgll, and Fell. The equilibrium and kinetic constants for formation of the dioxygen adducts of the cobalt(ii) chelates in aqueous solutions are also reported, and compared with previous data for the analogous macrocycles containing nitrogen, oxygen, and pyridine instead of sulphur. The values of log KML for the macrocyclic polyamines follow the trend N > S > 0. Oxygenation of the cobalt(ii) complexes of L4 and L5 yields p-peroxo-adducts as with the nitrogen and oxygen analogues, and the 0,-affinity order is N 3 S > 0.
