Compositions including one or more fluorochemical surfactants of the formula: (I) where R.sub.f is a perfluoroalkyl group, each of R.sup.1, R.sup.2 and R.sup.3 are C.sub.1-C.sub.20 alkyl, alkoxy, or aryl; and R.sup.4 is alkylene, arylene of a combination thereof. R.sup.4 is preferably an alkylene of 1-20 carbons that may be cyclic or acyclic, may optionally contain catenated or terminal heteroatoms selected from the group consisting of N, O, and S. Most preferably R.sup.4 is an alkylene of 2-10 carbon atoms. Described are anionic N-substituted fluorinated amine oxide surfactants, and use thereof in cleaning and in acid etch solutions. The cleaning and etch solutions are used with a wide variety of substrates, for example, in the cleaning and etching of silicon oxide-containing substrates.

Provided is a process for converting a hydrocarbon comprising at least one C—H bond to a nitrogen-functionalized product. The process comprises contacting a hydrocarbon and (i) an oxidizing electrophile comprising (a) a main group element or transition metal in oxidized form and (b) at least one nitrogen-containing ligand, or (ii) an oxidant and a reduced form of an oxidizing electrophile comprising (a) a main group element or transition metal and (b) at least one nitrogen-containing ligand, in a solvent to provide the nitrogen-functionalized product and an electrophile reduction product. Further provided is an oxidizing composition comprising the oxidizing electrophile with at least one nitrogen-containing ligand and a non-oxidizable liquid.
