Cerium(IV) ammonium nitrate in combination with sodium azide reacts with unactivated hydrocarbons in acetonitrile to furnish acetamides in one pot. The strategy can be used to introduce nitrogen functionality into a variety of compounds; a carboxylic ester directly afforded the corresponding α-amino acid.

The photosolvolysis of 9-fluorenol (1) and several of its derivatives, as well as related systems, has been studied in aqueous methanol and acetonitrile solutions.The primary aim of this study was to examine the effect of the internal cyclic array (ICA) of these compounds in promoting photosolvolysis with respect to the number of ? electrons available in the ICA.It was observed that 9-fluorenol derivatives photosolvolyze much more efficiently than any of the related systems studied in this work.In contrast, ground-state 9-fluorenol derivatives are the least reactive systems with respect to solvolysis.Quantum yields for methyl ether formation for photosolvolysis in 50percent MeOH-H2O are reported for 1-3.Rate constants for solvent-assisted photodehydroxylation (ks) are calculated on the basis of the proposed mechanism of heterolytic C-OH bond rupture in the primary photochemical step and are in the range (1.3-1.6)x1E10 s-1 for 1-3.

Treatment of secondary sulphinamides (1), bearing one hydrogen atom at α-carbon to nitrogen, with electrophilic reagents leads in some cases to formation of N-sulphenylimines (2), via a Pummerer-like reaction.

The reactions of organotin compounds with nitronium fluoroborate were investigated.It was shown that nitronium fluoroborate is an oxidizing agent in relation to the compounds Me4Sn, Bu4Sn, (cyclo-C6H11)4Sn, and RSnMe3 (R=m-CH3C6H4, 9-fluorenyl, 9-methyl-9-fluorenyl), and the reaction products have radical nature.The reaction of nitronium fluoroborate with PhCCSnMe3 leads to the formation of oxidation and substitution products.
