N—[2—(5,5-Diphenyl-2,4-imidazolidinedion-3-yl)ethyl]-7-acetoxy-1-napthalene sulfonamide This substituted sulfonamide has a molecular weight of 543 daltons, and in the positive LD mass spectrum two ions at m/z 566 and m/z 582, corresponding to attachment of sodium and potassium ions, respectively, were observed. No significant photodissociation pathway other than loss of the attached cation was seen for either of these two ions. In the negative ion LD mass spectrum, an ion at m/z 500 originating from loss of C HjO was observed. This ion photodissociated when irradiated by the (gated) cw laser to produce an ion at m/z 251 (see Figure 9) (Equation 6).

Sodium napthalene solutions in tetrahydrofuran solvent have been used to provide surface treatment of fluorocarbon surfaces for several decades. A commercial surface treatment based on this process has been Tetra-Etch.63 Recently the manufacturers of Tetra-Etch introduced Fluoro-Etch, which has several advantages. Fluoro-Etch requires no refrigeration, is easier to handle, and offers significant cost, efficiency, and safety advantages. It offers a 1-year shelf life and is manufactured in both the United States and Europe. 

Reduction of /rcMr-RuCl2[Me2PCH2)2]2 by arene radical anions such as sodium naphthalide has been shown to lead to a series of hydridoaryl complexes of the type Ru(H)(aryl)[(Me2PCH2)2]2 63). The hydride structure of the napthalene derivative has been shown in solution (63) and in the solid state 232). However, on the basis of the chemistry of the complexes, the following equilibrium was proposed 63), between a hydride and a small amount of a dihapto-coordinated arene-Ru(O) complex ... 

Interest in the use of reducing agents to activate C-F bonds was revived when systems that enabled selective removal of fluoride from perfluorocarbons were discovered in contrast to the complete (destructive) removal of halides as in sodium fusion reactions employed in methods for halogen analysis [31]. (Interest in this latter area has also had resurgence in the search for methods capable of destroying chlorofluorocarbons [32].) The key breakthrough was the report by MacNicol and Robertson that hexakis(thiophenoxy)napthalene can be prepared by treatment of perfluorodecalin with excess sodium phenylthiolate for 10 days at 70°C in DMF [33].

The standard must be carefully chosen and it should ideally possess the following properties have a simple spectrum with very few bands be stable to heat and not absorb moisture be easily reduced to a particle size less than the incident radiation without lattice deformation be non-toxic, giving clear discs in a short time be readily available in the pure state. Some common standards used include calcium carbonate, sodium azide, napthalene and lead thiocyanate. 

Liquid etchants can be used for chenucal modification or dissolving surface contamination. Etchants effectively treat irregularly shaped objects that are difficult to treat by other adhesion-promoting processes such as corona or flame treatment. A number of etching solutions and procedures have been developed for specific polymeric surfaces. The choice of the liquid etchant depends on the polymers. Polyolefins are usually treated by oxidizing acids such as chromic, sulfuric, nitric, or mixtures of these. Fluorocarbons are usually treated by sodium-napthalene etching solution.
