Metal coordination to a dimetallaoctatetrayne

Delaney, Andie; Frogley, Benjamin; Hill, Anthony

Description

The reactions of the ditungstaoctatetrayne [(Tp*)(CO)2W([triple bond, length as m-dash]CC[triple bond, length as m-dash]CC[triple bond, length as m-dash]CC[triple bond, length as m-dash])W(CO)2(Tp*)] with several metal complexes have been investigated. Addition of [Co2(CO)8] occurs across the internal C[triple bond, length as m-dash]C bonds, whereas [AuCl(SMe2)] initially delivers 'AuCl' across the W[triple bond, length as m-dash]C carbyne bonds before undergoing further reaction to oxidise the...[Show more]

dc.description.abstractThe reactions of the ditungstaoctatetrayne [(Tp*)(CO)2W([triple bond, length as m-dash]CC[triple bond, length as m-dash]CC[triple bond, length as m-dash]CC[triple bond, length as m-dash])W(CO)2(Tp*)] with several metal complexes have been investigated. Addition of [Co2(CO)8] occurs across the internal C[triple bond, length as m-dash]C bonds, whereas [AuCl(SMe2)] initially delivers 'AuCl' across the W[triple bond, length as m-dash]C carbyne bonds before undergoing further reaction to oxidise the tungsten and replace the carbonyl ligands with chloride in [(Tp*)Cl2W([triple bond, length as m-dash]CC[triple bond, length as m-dash]CC[triple bond, length as m-dash]CC[triple bond, length as m-dash])WCl2(Tp*)] with retention of the ditungstaoctatetrayne bridge. Reaction with [AuCl(PR3)] (R = Ph, Cy) in the presence of AgPF6 prevents this oxidation and adds [AuPR3]+ across the W[triple bond, length as m-dash]C bonds to give dicationic derivatives. Finally, the reaction with [Pt(nbe)3] (nbe = norbornene, bicyclo[2.2.1]hept-2-ene) and 1,5-cyclooctadiene (COD) adds a 'Pt(COD)' unit to one or both tungsten-carbon bonds, allowing both the mono- and diplatinum complexes to be isolated.
