Incorporation of coinage metal-NHC complexes into heptaphosphide clusters

Cu( i ) and Au( i ) ions, capped with an N-heterocyclic carbene (NHC), react with (TMS) 3 P 7 (TMS = trimethyl-silyl) to afford an η 4 -coordinated anion [NHC Dipp Cu-P 7 (TMS)] − and a neutral trinuclear complex (NHC Dipp Au) 3 P 7 . Protecting the P 7 cage with the TMS groups is instrumental in co...

Zusammenfassung:Cu( i ) and Au( i ) ions, capped with an N-heterocyclic carbene (NHC), react with (TMS) 3 P 7 (TMS = trimethyl-silyl) to afford an η 4 -coordinated anion [NHC Dipp Cu-P 7 (TMS)] − and a neutral trinuclear complex (NHC Dipp Au) 3 P 7 . Protecting the P 7 cage with the TMS groups is instrumental in controlling the course of these reactions. A Me 3 Si-protected P 7 cage reacts with N-heterocyclic-carbene complexes of coinage metals to yield a mononuclear Cu( i ) complex featuring a Cu(η 4 -P 7 ) core and a trinuclear Au( i ) complex with linearly coordinated metal ions attached to the P 7 cluster.
