This article is prompted by developments in the chemistry of allenyl complexes their systematic synthesis, structural diversity, and patterns of chemical reactivity. The increasing attention being focused on allenyl and allenylidene compounds can be attributed to several factors an upsurge in interest in cumulene ligands in general and electronic communi-...

Table VI lists several of the characteristic C NMR parameters used for structural elucidation of allenyl and propargyl complexes. The distinctive C chemical shifts (8C) and associated Jch values of allenyl complexes have been used to distinguish different bonding types. The aileny-lic - C methylene signal appears downfield of the corresponding...

Fig. 23) to give an allenyl complex this reacts with CH3OH forming a binuclear structure comparable with that of Fe2(CO)6(C2Et2COO).l ... 

The addition of a carbanion to an allenyl complex leads to a trimethylenemethane derivative that has been isolated, and its structure determined by X-ray crystallography (Equation (51)). ... 

The first single crystal structure and convenient synthesis of zwitterionic Ti -trimethylenemethane palladium complexes derived from nucleophilic addition of caibanions to an allenyl complex has been reported. ... 

The binuclear allenyl complexes [M2(CO)6(lt-PPh2)( X-Ti tl2p,y-C(Ph)=C=CH2)] (M = Ru, Os), obtained from the reaction of [M2(CO)6(lt-PPh2)( 4- n n -C CPh)] with diazomethane have been shown to have unprecedented structures in which Ca is a-bonded to one metal site while the Cp-Cy double bond is coordinated to the second metal. Reactions of the product were...
