Die Additionsfahigkeit der Ni-C-o-Bindung in 1 gegeniiber CC-Mehrfachbindungssystemen ist ebenfalls schon bei 20°C sehr ausgeprlgt. So wird nach Zugabe von Allen zu einer THF-Losung von 1 durch Insertion der q3-Allylkomplex 4 gebildet [95%; Fp=82"C (Zers.); Ir (KBr): v= 1635 (C=O), 3130 cm-' (N-H)]. 4 laat sich zu N,N-
The first metal‐induced synthesis of an acrylic acid derivative 4 from a non‐activated alkene 1 and an isocyanate 2 takes place via CC coupling to give an azanickelacyclopentanone 3. 4 is immediately formed upon heating 3.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
