Materials science research coupling reactions

The chemistry of diazines remains an area of intense interest, both academic and industrial, with applications in many areas, from biomedical to materials science and electronics. They are versatile, having very varied reactivity, giving many opportunities for manipulation of substituents. Nucleophilic substitutions, electrophilic substitution in oxy and amino derivatives, organometallic and transition metal-catalysed coupling reactions are all subjects of substantial research effort. There are obvious similarities in reactivity of the three diazine systems but also many interesting and practically important, often subtle, differences. 

The first three of the following papers in this symposium are concerned with coupling agents. These investigations were stimulated by the reaction of an NRL team of surface chemists to the published industrial research of the past decade on glass-reinforced plastics and other composite materials. Present commercial practices still appear to involve more art than science (63), and these papers give adequate evidence that there are opportunities for both basic and applied research on the subject.
