Abstract
DEVELOPMENTS in the theory and practice of organic chemistry during the past ten years have opened up a new and broader outlook on organic reactions in general. The reactions of classical organic chemistry, which in the main are concerned with reactions between two molecules or with reactions between an ion and a molecule, have been embraced within a comprehensive electronic theory, the main features of which were firmly established about fifteen years ago. To-day many examples are known of reactions which do not possess the characteristic features of the electronic processes generally referred to as 'electrophilic' or 'nucleophilic', and it is now necessary to consider a third type of reaction, namely, those between a molecule and either an atom or a free radical. Provision for this third type of reaction is obviously necessary, since it is possible to sever a covalent bond in one of two ways, resulting in heterolysis or homolysis, thus:
