Abstract

On irradiation in the presence of Fe(CO)5, the allenic amides and imides showed a similar course of complexation to that of esters and lactones, respectively, e.g. the amides of type 10 led to diiron complexes of type 11 (Scheme 3 ), whereas the imide 12 yielded a mixture of a dinuclear and two mononuclear complexes (13-15, Scheme 4). The racemic ester 6 also gave mononuclear (7a, 7b, and 9) and dinuclear complexes (8a and 8b; Scheme 2). In case of the allenic acid 4, only complexation of type 5 was observed (Scheme 1).

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
