Rhodium(I) Complexes of N-Aryl-Substituted Mono- and Bis(amidinates) Derived from Their Alkali Metal Salts

The synthesis and characterization of several rhodium(I) complexes of amidinate and linker-bridged bis(amidinate) ligands are presented. The amidinate ligands for the mononuclear complexes CH3{C(NMes)2Rh(cod)} (1), CH3{C(NDipp)2Rh(cod)} (2), and HCC{C(NDipp)2Rh(cod)} (3) (cod = 1,5-cyclooctadiene) were synthesized by reacting the corresponding organometallic precursor [Rh(cod)Cl]2 with the alkali metal amidinates CH3{C(NR)2Li} L1Li (R = Mes = 2,4,6-Me3C6H2) and L2Li (R = Dipp = 2,6-iPr2C6H3). Analogously, the alkynyl-functionalized sodium amidinate (HCC{C(NDipp)2Na}·2DME, L3Na) could be further deprotonated and reacted with carbodiimine to form the alkyne-bridged bis(amidinate) CC{C(NDipp)2Na(thf)}2 (L4Na), which serves as suitable starting material for the synthesis of CC{C(NDipp)2Rh(cod)}2 (4). The bis(amidinate) ligands for the corresponding para- (5) and meta- (6) phenylene-bridged complexes p-/m-C6H4{C(NMes)2Rh(cod)}2 were accessible through the reaction of phthalic acids with trimethylsilyl polyphosphate and mesitylamine and subsequent deprotonation of the obtained amidines. Tetramesityl oxalamidinate was used to synthesize the dinuclear complex {C(NMes)2Rh(cod)}2 (7) and its carbonylation product {C(NMes)2Rh(CO)2}2 (8). All compounds under study were fully characterized by various spectroscopic methods. In particular the alkali metal salt of the linker-bridged bis(amidinate) L5Na forms a one-dimensional coordination polymer in the solid state. Reaction of L5Na and L6Na with [Rh(cod)Cl]2 leads to dinuclear complexes in which the metal–metal distance can be adjusted, enabling us to study their reactivity, including possible cooperative effects in catalysis.
