Nitrogen discovery constitution

The development of the new field of organometal chemistry during the last two decades has led to the discovery of many unusual organometal complexes which are soluble in organic solvents. The ability of some of these complexes to react with molecular oxygen or with molecular nitrogen imder very mild conditions has been of particular interest because the complexation of these simple but ubiquitous molecules to transition metals constitutes the first step in two of the most... 

Blomstrand then mentioned that Griess had found that in acidic solution, instead of diazoaminobenzene, a salt of "diazobenzol" is formed, a discovery which had led to azo compounds, which even in 1869 were already technically important. Of course Kekule had theoretically explored all these new organic nitrogen compounds and, "with his ordinary perspicacity completely disentangled their constitution" (2, p. 271), as Blomstrand ironically expressed it. He then cornered Kekule by comparing Kellie s way of describing the the diazotization of aniline with his own ...
