The main group and coordination chemistry of N-silylated benzamidines, RC 6 H 4 C (
NSiMe 3)[N (SiMe 3) 2], and the corresponding anions,[RC 6 H 4 C (NSiMe 3) 2]−, is …

Biradicals are molecules consisting of two unpaired electrons in two nearly degenerate non-
bonding molecular orbitals (NBMOs). They play a central role in bond breaking and …

This question could be answered by just stating that the molecules 1, 2 and 3 are all
heterocyclic mesomeric betaines. This general answer, however, conceals an informative …

This review describes recent advances in the development of thiazyl radicals, particularly
dithiadiazolyl (RCNSSN) and dithiazolyl (RCSNSCR) as molecule-based materials …

Chalcogen-nitrogen chemistry involves the study of compounds that exhibit a linkage
between nitrogen and sulfur, selenium or tellurium atoms. Such studies have both …

Although there have been several brief review articles on dithiadiazolylium chemistry
(92CBR148, 92MI1, 92MI2), this is the first comprehensive overview. The steadily increasing …

This review is a critical overview of the literature on electrochemistry of unsaturated ring-
compounds containing bonds between Group 15 and Group 16 elements (principally S and …

The relationship between heterocyclic mesomeric betaines (HMBs) isoconjugate with
hydrocarbon dianions and pairs of alternant hydrocarbon fragments is recognised. An …

During the last 15 years thestudy of sulfur-nitrogen (SN) compounds has progressed from
relative obscu-rity to a position in the vanguard of main-group chem-istry. In part, this rise to …

Valence bond structures depicting localized two-centre, twoelectron 0 and 7~ bonds have
proved to be an extremely useful concept for discussing the structures and reactions of …
