Unusual, Bifurcated Photoreactivity of a Rhenium(I) Carbonyl Complex of Triethynylphosphine
Preparations of the first metal complexes of triethynylphosphine (TEP) are described. They are of the type fac-Re(bpy)(CO)3(TEP)+ (1) and cis,trans-[Re(bpy)(CO)2(TEP)L] n + (CH3CN, n = 1, complex 2; Cl, n = 0, complex 3), where bpy is 2,2‘-bipyridine. Complex 1 displays unusual photochemical behavio...

Summary: | Preparations of the first metal complexes of triethynylphosphine (TEP) are described. They are of the type fac-Re(bpy)(CO)3(TEP)+ (1) and cis,trans-[Re(bpy)(CO)2(TEP)L] n + (CH3CN, n = 1, complex 2; Cl, n = 0, complex 3), where bpy is 2,2‘-bipyridine. Complex 1 displays unusual photochemical behavior compared to analogous fac-[Re(bpy)(CO)3(PR3)]+ complexes in that it emits from a state that has π−π* character but undergoes competitive photosubstitution of both TEP and CO. Density functional theory (DFT)/time-dependent DFT calculations predict that the lowest emitting state should, in fact, have π−π* character. |
