Neutral organic reaction intermediates carbenes

Carbenes. Although most organic compounds possess uncharged carbon atoms that have a Lewis octet of electrons in their valence shells, i.e., they form four bonds, neutral carbon fragments can nevertheless be generated as reaction intermediates. These include carbenes. The generation of transient carbene ICs is explored in detail in this chapter. 

Information is also given for excited neutral radicals. Several recent reviews have described the reactions of excited radicals, radical ions, biradicals, carbenes, ylides, and other intermediates. Neutral radicals derived from organic systems...
