By M. Kaloustian

Within the final sector century there were merely seminal contributions within the box of natural stereochemistry - either via Kurt Mislow and his coworkers - ones that experience clarified the elemental strategies of stereotopicity and chirotopicity. no longer withstanding a couple of different sporadic contributions by means of others, up to now there were no systematic makes an attempt to unify and advance the conceptual framework and terminology of natural stereochemistry. latest phrases are usually misused or abused, wanted phrases - redundant, complicated or arguable - are invented randomly, and but different wanted phrases haven't noticeable the sunshine of day. This three-part paintings offers the weather of an easy, uniform and complete language of the stereochemical underpinnings of natural chemistry. it's crucial studying for commercial chemists, graduate scholars, college professors and commercial researchers within the box of natural Stereochemistry.

Ligogenic/Ligolytic Processes Guest-host decomplexation 3-»l+2, 7t-decomplexation 6-»4+5, and dissociation of H-bonded dimers 8-*7a+7b are disjunctive but they not ligolytic because no distinct a bonds, or o/7l-bonds, is(are) broken in any one of them. Overall transformations ll-»9+10, 13-»12a+12b, 16-» 15+14, 19-» 17+18, and 22-* 20+21 represent typical ligolytic processes, since each one of them involves (total) cleavage of a o or a+n bond. Every ligolytic process, starts out as a dissociative process with severance of a c or a+n bond along the reaction coordinate, and terminates with the final disjunction of the molecular entities.

It is of course possible to define Jfor and Jrev for unbalanced equations; here, the comparison would be between similar (and similarly unbalanced) processes. The concept of the junctivity lays the framework for discussing the concepts of ligogenicity (Chapter 9), vectoselectivity (Chapter 13), and regioselectivity (Chapter 13). 26 XI. Usefulness of the Concept of Junctivity A. Valency, Coordination Number and Atom Junctivity The concept of atom junctivity differs from the concepts of valency and coordination number.

Jfor and Jrev for Various Junctive/Disjunctive Transformations In sum, Jfor is a quantitative index of the efficacy of construction of assembled frameworks; t h e more positive the Jfor value, the higher the degree of association or assembly. The efficacy of t h e breakdown of organic frameworks is also quantitatively assessed in terms of Jfor; the more negative the Jfor value (the more positive the Jrev) is, the greater the extent of disassembly would be. Examples 244,250,254,258,261,265,270,274 have Jfor values of 4-12, indicative of relatively h i g h degrees of junctivity.
