Donor properties of nitroso compounds. I. Complexes with p-nitroso-N,N-dimethylaniline

Abstract

of the it* orbitals in quinoline 1-oxides relative to pyridine 1-oxides. Hence, ir back-bonding (metal to ligand) becomes increasingly important in the quinoline 1-oxide complexes. ConclusionsThe data indicate the importance of a -back-bonding (metal-to-ligand) interaction. It is interesting that Donor Properties op Nitroso Compounds 1845 this interaction is much more important in quinoline 1-oxides than in pyridine 1-oxides. In addition bonding seems to be more important for isoquinoline 2-oxide than for pyridine 1-oxide. The addition of the aromatic ring in the quinoline ring system helps to delocalize electrons and lowers the t* molecular orbitals in this system significantly, thereby creating more effective T overlap with the metal ion.

Nitrosoalkanes as new ligands of iron(II) porphyrins and hemoproteins

“…(4) Two different collections of L. snyderiae, one from La Jolla and one from Santa Catalina Island, were compared. La Jolla populations contained concinndiol (2) as well as 3-snyderol (3), the structure of which was reported in an earlier communication (B. M. Howard and W. Fenical, Tetrahedron Lett., 41 (1976)). Santa Catalina Island populations also contained 2 and 3, but they contained, in addition, the hydroperoxide 1 and an aromatized snyderol derivative, 4, reported earlier as a component of L. nidifica ( .…”

“…The fiveand six-membered rings are trans fused, and the relative stereochemistry at C(5), C(8), C(9), C(10), and C( 13) is identical with that reported for 2. 3 Additional crystallographic details can be found in the supplemental material.…”

Reactivity of 4-Nitrosoanilines Towards Dimeric Halogenido-bridged Complexes of Iridium(III) and Rhodium(III) of the Type [(η5- C5Me5)MX2]2

“…These aromatic C-nitroso compounds show remarkably high reactivity because the amino group in para-position increases the electron density at the NO function [24]. Complexes containing these ligands are known for different metal centers and coordination modes as published by our group [25,26] and others [8,9].…”

Synthesis and Properties of Substituted 2-Amino-5-nitrosobenzylamines

“…One protonation center is the oxygen atom in the nitroso group [5,6], for the electron absorption spectra of amines IIIV and VI lack absorption corresponding to n,p* transition of the nitroso group at l 650750 nm. We examined the basicity of amines IIIV and VI by potentiometric titration.…”
