Özet
Diazocarbonyl compounds are versatile precursors of carbenes leading to various structures by using several metal catalysts, especially copper and rhodium salts. In this study, eight different diazocarbonyls having N-O moiety were used. The N-O tethered structures were prefened because they may allow some useful transformations of the final products into valuable compounds via N-O cleavage. In the presence of a double bond on the -OR function of the starting diazo compound, CuCl/AgSbF6 catalyst yielded only cyclopropyl fused oxazinane/oxazepane derivatives over cyclopropanation while Rh-2(OAc)(4) catalyst was giving mainly isooxazolidinones via C-H insertion.
