Generation and reactivity

Mu/tihearth Furnace. Multihearth furnaces are most often used for incineration of municipal and industrial sludges, and for generation and reactivation of char. The main components of the multihearth are a refractory-lined shell, a central rotating shaft, a series of soHd flat hearths, a series of rabble arms having teeth for each hearth, an afterburner (possibly above the top hearth), an exhaust blower, fuel burners, an ash removal system, and a feed system. 

For discussions concerning their structure and further information on the generation and reactivity of arynes the reader is referred to a series of published reviews. ... 

The data described above give sound evidence for the existence of 3,4-pyridyne but do not indicate that 2,3-pyridyne occurs as an intermediate. The generation and reactivity of 3,4-pyridyne and some of its derivatives are discussed next. Section II, A, 3 deals with problems concerning 2,3-pyridyne.

The electrochemical generation and reactivity of phosphoniumyl and related charged radicals have been recently reviewed by Kargin and Bunikova [8]. In 1995, Yasui reviewed the reactivity of trivalent phosphorus compounds in single electron transfer (SET) processes [41] and, in 1990, the EPR features and reactivity of phosphoniumyl radicals were reviewed by Tordo [42].

During the past decade a very considerable literature has developed concerning the generation and reactivity of alkyl and alkylidene groups adsorbed on metal single-crystal surfaces produced via the photochemical or thermal decomposition of adsorbed alkyl halides or nitrogen-substituted alkanes. In this review, we concentrate on publications which exhibit VEEL or RAIR spectra of the hydrocarbon groupings that can be used as reference spectra for the identification of such species in spectra of species derived from hydrocarbon chemisorption. Reviews of such work cover the kinetic as well as spectroscopic aspects of this area of research (142-144).

The independent generation and reactivity of allenic enolates has been investigated.15 Under kinetic conditions, these highly reactive species are protonated in the a,p-7t plane with preference (E) to the larger ( group. Under thermodynamic con- (g) ditions, addition/elimination equilibrates the two product stereoisomers. The kinetic protonation stereochemistry has been found a function of solvent, proton donor, and donor concentration. 

The generation and reactivity of conjugated azomethine ylides has been reviewed.148 1,3-Dipolar cycloaddition and 1,5- and 1,7-electrocyclizations have been described as powerful strategies for the synthesis of monocyclic and annulated five- and seven-membered nitrogen heterocyclic compounds.
