Classification of Organic Reactions

The method is incorporated into the CORA (Classification of Organic Reactions for Analysis) system [Sf Here, wc want to illustrate the merits of this approach by an example of its application to a specific problem, the prediction of the regioselec-tivity of a ring closure reaction. This is detailed in the following tutorial. 

Kinds of Catalyzed Organic Reactions A fundamental classification of organic reactions is possible on the basis of the lands of bonds that are formed or destroyed and the natures of eliminations, substitutions, and additions of groups. Here a more pragmatic hst of 20 commercially important lands or classes of reactions will be discussed. In all instances of sohd-catalyzed reactions, chemisorption is a primary step. Often molecules are dissociated on chemisorption into... 

Many reactions of purely theoretical interest have been incorporated, so that the student may gain some real idea of the possibilities of his subject, and that he may feel his practical and theoretical text-books to be very near akin. Indeed, the authors trust that from a theoretical standpoint alone the student may find the book useful in that it will enable him to view his subject from an angle different to the usual, and in this way to gain perspective. The better to accomplish this, they have introduced a new classification of organic reactions in which reaction follows reaction on a definite plan. They hope that the student who... 

A category of reactions with a characteristic irreducible R-matrix is a set of basis reactions. The basis reactions correspond to the traditional classification of organic reactions . A basis reaction is best characterized in graph theoretical terms (ref. 13). The educts and the products of a basis reaction are expressed by a graph (see Fig. 7.2) whose nodes correspond to the reactive centers and whose lines indicate the bond orders of the covalent bonds that are directly affected by the reaction. The... 

The field of carbenes has been intensively investigated for the last two decades b. These studies have shown that carbenes as well as nitrenes and arynes play an important role in organic chemistry as reactive intermediates 2). Not only have these studies made it possible to understand many organic reactions in detail, they have also given use to a simple classification of organic reactions on the basis of these reactive intermediates.

To make such compounds we need to be able to introduce these double bonds into molecules in a controlled manner. One way of doing this is by elimination. Cast your mind back to the classification of organic reactions that we set out at the start of Part 2 of this book.
