Azane oxides

Asymmetric /) .vamidocyclodiphosph(V,III)azane monochalcogenides (40), containing a phosphorus (V) and a phosphorus (III) centre, are accessible from stoichiometric oxidation of the parent feamidocyclodiphosphazane with... 

The first cyclopnict(V)azane, reported by Roesky and coworkers in 1983, was the arsenic compound 33, obtained by oxidative addition of CI2 and concomitant trimethyl(chloro)-silane elimination from a bis(trimethylsilyl)amidoAs(III) precursor. Equation (10.11). Each As atom in crystalline 33 is in a trigonal bipyramidal environment (Cl and axial) there is a rhomboidal (AsN)2 core, with the As—longer than the As-Neq bonds [a feature which is replicated in the (Sb N)2 compounds 34, 35, and 36, but differs from the (M N)2 compounds of Section 10.3.1]. Thermolysis of 33 yielded the crystalline compounds [As(CF3)2(p-N)] ,. (v = 3 or 4). ...

The compound is obtained by means of direct nitrating of benzofur-azan-1-oxide with concentrated nitric and sulfuric acid, or by heating -> Trinitrochlorbenzene (Picrylchloride) with sodium azide in acetic acid in a water bath. 

Nelsen and coworkers [562] detected conformational equilibria in eq, eq- and ax, eq-N, A -disubstituted cyclic hydrazines from their oxidation potentials. The anodic oxidation reactions of trans- and cw-l,3-diisopropy-l-2,4-bis(diisopropylamino)-cyclodiphospha(III)azanes are quite different [563] The trans isomer is reversibly oxidized at 0.53 V (SCE) forming a stable cation radical the c/5-isomer undergoes a completely irreversible oxidation at a more positive potential because an unstable radical cation is formed. Evans and coworkers studied structural changes associated with electron transfer reactions of W(// -C5(CH3)5)(CH3)4 and related compounds [564,565]. Yoshida and coworkers found a linear correlation on plotting the oxidation potentials of a-silylated ethers, where the rotation around the C-0 bond is restricted, against the HOMO energy-torsion angle (Si-C-O-C) curve estimated by MO calculation [566].
