Introduction

It is in general well known that alkanoyl peroxides [R-C(=O)–O–O–(O=)C-R; R = alkyl group] decompose homolytically via a stepwise radical fission to produce an acyloxy radical [R-C(=O)O•] and finally an alkyl radical (R•), as shown in Scheme 1.1. However, interestingly, fluoroalkanoyl peroxides [R-C(=O)–O–O–(O=)C–RF; RF = fluoroalkyl group] can decompose homolytically through three-bond radical fission to afford fluoroalkyl radicals (RF•; see Scheme 1.2). This unique decomposition mechanism has already been applied as a radical initiator for fluoroolefins such as tetrafluoroethylene to produce thermally stable fluorinated polymers. The thermal stability of the fluorinated polymers thus obtained is due to the direct introduction of fluoroalkyl segments (RF) related to the peroxide into the fluorinated polymer end-chains (RF-CFC2F2~) during the radical polymerization process of fluoroolefins initiated by fluoroalkanoyl peroxides. The thermal decomposition of fluoroalkanoyl peroxides selectively affords the corresponding coupling products (RF-RF) in good yields, indicating the formation of RF• radicals during the decomposition process (see Scheme 1.2), although the corresponding non-fluorinated alkanoyl peroxide affords the ester products [R–C(=O)OR] through stepwise radical decomposition fission (see Scheme 1.1).

Another specific characteristic of fluoroalkanoyl peroxides is that they are useful electron acceptors even from well-known relatively poor electron-donor aromatic compounds such as benzene, chlorobenzene and heteroaromatic compounds such as thiophenes and furan to proceed via a single electron transfer reaction from these aromatic compounds to the peroxide. As shown in Scheme 1.3, this single electron transfer reaction permits the direct introduction of a fluoroalkyl group (RF) related to the peroxide into the corresponding aromatic compounds in good yields. In this way, fluoroalkanoyl peroxides can exhibit considerably different properties from those of the corresponding non-fluorinated compounds.

It is of great interest how fluorination improves the reactivity of alkanoyl peroxides so substantially. For the understanding of the effects of fluorination, it is useful to elucidate the electronic structures of alkanoyl and fluoroalkanoyl peroxides, because the alkyl and fluoroalkyl groups exhibit significantly different electronic properties, especially a much higher electro-negativity of the fluorine atom than the hydrogen atom. In this chapter, the electronic structure of alkanoyl/fluoroalkanoyl peroxides is studied computationally using ab initio molecular orbital methods. In 1990, Sawada et al. performed a computational study of these peroxides using a semi-empirical molecular orbital method, in which some parameters were determined from experimental data. Ab initio methods, on the other hand, use no empirical parameters in the calculation of molecular electronic structure. The advantage of ab initio over semiempirical methods is that one can systematically improve the accuracy of the molecular wavefunction, in principle, towards the exact solution of Schrodinger equation. An ab initio method involves a much larger computational cost than a semiempirical method. Owing to recent progress in computer technology, however, today it is not difficult to carry out ab initio calculations on alkanoyl/fluoroalkanoyl peroxides when the size of the alkyl/fluoroalkyl group is relatively...
