Novel RhI Piano‐Stool Complexes with New Hemilabile Ligands Ligating through Phosphane and Arene Groups: Synthesis, Characterization, and Reactivity

Abstract: Which arene ligand coordinates? An intramolecular exchange previously unknown for RhI complexes in which the phenyl ether moieties bind alternately in an η6 fashion to the Rh1 center (in 1 and 1' on the right) is observed by two‐dimensional 1HNMR exchange spectroscopy. This exchange of the aryl ether‐phosphane ligands probably proceeds via intermediate 2 and therefore cannot be detected when the O atoms are exchanged for CH2 groups.

“…Our group has introduced and focused on developing one of these strategies, which is referred to as the Weak-Link Approach (Scheme 1). This strategy allows one to prepare bimetallic macrocycles from simple transition metal and ligand precursors (7)(8)(9)(10)(11)(12), and it is based on reactions between flexible symmetrical hemilable ligands (13)(14)(15)(16) and transition metal precursors. Typically, macrocyclic intermediates that contain both strong (S-M) and weak (W-M) ligand-metal bonds (Scheme 1) are initially formed in very high and usually quantitative yield.…”

“…Diphenyl(3-phenylpropyl)phosphine, (I), is a potentially chelating ligand that has been prepared by several groups for the study of tethered arene-Rh I and Ru II complexes of the type [Rh{η 1 -Ph 2 P(CH 2 ) 3 C 6 H 5 }{η 1 :η 6 -Ph 2 P(CH 2 ) 3 C 6 H 5 }] (Singewald et al, 1994(Singewald et al, , 1996 and [RuCl 2 {η 1 :η 6 -Ph 2 P(CH 2 ) 3 C 6 H 5 }] Ghebreyessus & Nelson, 2000;Smith & Wright, 1998). (I) may coordinate to the metal centre through both the phosphorus donor atom and the alkyl arene.…”
