Preparation and properties of a new class of halo(carbonyl)(phosphine)(π-allyl)nickel complexes are discussed. All the possible equilibria appear to exist in solution. Evidence is given that pentacoordinated intermediates are involved in carbonylation reactions

The reactivity of a nucleophilic nickel acylate complex with a tungsten carbene complex, Fe(CO)5, Cr(CO)6, PPh3, and CO was investigated. With the tungsten carbene complex, a methyl transfer occurred. With the metal carbonyl complexes, the acylate group on the nickel and a carbonyl on the iron or chromium traded places. With the PPh3 and CO, the acylate anion was replaced by the phosphine or CO ligand
Expanding the phosphorus–carbon analogy: formation of an unprecedented 5-phosphasemibullvalene derivative

We could access for the first time a 5-phosphasemibullvalene derivative by quantitative and selective photochemical di-[small pi]-methane rearrangementfrom the corresponding phosphabarrelene. Due to the striking analogy between phosphorus and carbon,...
The structure of the novel η1-η2 complex [(CO)4Fe]2(RPCH2) (R = 2,4,6-tri-t-butylphenyl) has been determined by X-rayanalysis. Furthermore, the Fe complexes [(CO)4Fe](RPCH2) were identified. The phosphaalkene RPCH;; forms the η1 complex [(CO)3Ni](RPCH2) with Ni(CO)4.

Both tetraarsenic and tetraphosphorus hexamethylimide react with nickel tetracarbonyl to form complexes in which from one to four tricarbonylnickel groups coordinate with the arsenic or phosphorus atoms. The totally coordinated species are crystalline and insoluble in all common solvents whereas the other complexes have only been investigated in solution. Evidence is presented to show that complexing
