The first step of electrochemical oxidation of 2-phenyl- and 2-(4-tolyl)-1,3,4,7-tetramethylisoindoles in anhydrous acetonitrile produces relatively stable cationradicals which have been studied by means of EPR spectroscopy using the method of internal electrochemical generation of radicals under reduced temperature. The same electrochemical behaviour of the both studied derivatives and identical EPR spectra of their cationradicals can be explained within the Huckel MO method. The largest contribution to the magnitude of splitting constant of nitrogen nucleus is due to π-σ-spin polarization of C-N bonds caused by high spin abundance of pz-AO of carbon atoms. Half-life of decomposition of the studied cationradicals is 4 min at -30°C.

This chapter examines the phonological rule of nasal substitution in Tagalog, specifically its rate of application in different constructions. Nasal substitution can occur whenever a prefix that ends in /ŋ/ attaches to a stem beginning with an obstruent, as in /maŋ + bigáj/ → [mamigáj] ‘to distribute’. Different prefixes trigger nasal substitution at different rates. This is similar to cases in which word-internal syntactic structure determines how and whether a phonological rule applies (e.g. Newell and Piggott 2014), but different because none of these words’ syntactic structure absolutely prevents nasal substitution, such as by placing a phase boundary between the prefix and stem. The focus of the chapter is on laying out the data, but it does suggest three possible interpretations: variable syntactic structure, a phonology directly sensitive to prefix identity, or competition between productive syntactic structure and lexicalized pronunciation.
