Diazoalkanes structural chemistry

It has been shown that [(r]6-arene)RuCl2]2 6 and [(r 6-arene)RuCl2] PR3 7 complexes can be activated in situ to afford active metathesis catalysts, either on treatment with diazoalkanes [15] or by UV irradiation [16]. The structure of the active species thus formed is unknown, but it initiates the ring opening metathesis polymerization reactions (ROMP) of various cycloalkenes very efficiently. Therefore these in situ recipes may also be useful in the context of preparative organic chemistry. [Pg.55]

Staudinger s historical merits for our knowledge of diazoalkanes, based on his work between 1911 and 1921, became somewhat overshadowed by his later and clearly more fundamental and pioneering ideas about the formation and structure of macromolecules (Nobel Prize 1953). It should be emphasized, however, that his development of the concept of polymerization was, at least in part, based on his observations of the formation of polymethylene in the dediazoniation of diazomethane. Macromolecular chemistry, therefore, appears to be a child of early diazo chemistry ... [Pg.5]
