The Charge and Spin Transfers in Chemical Reaction Paths

Abstract

The role of the interaction of particular molecular orbitals (MO) in chemical reactions in general has long been recognized as an essential factor determining the orientation (Fukui et al., 1952, 1954a; Fukui, 1964, 1965a, 1970a, b, 1971b; Klopman and Hudson, 1967; Klopman, 1968; Salem, 1968, 1969a, b). The interaction of particular MO{\rq}s also relates to the stereoselection rule and is believed to control the stereochemical path (Fukui, 1964, 1965b, 1971a; Woodward and Hoffmann, 1965, 1969a, b; Fukui and Fujimoto, 1969a; Anh, 1970), and the mechanism of such particular MO controls has qualitatively been discussed in relation to the nature of chemical reactions (Fukui et al., 1954b; Fukui and Fujimoto, 1968, 1969b; Fujimoto et al., 1971b; Fujimoto and Fukui, 1972).
