Synthesis and catalytic activity of monobridged bis(cyclopentadienyl)rhenium carbonyl complexes

AB - A regioselective cyclization of 1,n-diynes under rhenium catalysis was developed on the basis of a rare type of 1,1-difunctionalization of terminal alkynes with carbon nucleophiles, followed by sequential addition reactions of the resulting alkenylrhenium species. The reaction provides an efficient approach to the synthesis of complex cyclopentane-fused bi- and tricycles and spirocycles, which are useful building blocks for the construction of essential frameworks of biologically active compounds as well as functional materials, from simple starting materials by the formation of up to six new carbon–carbon bonds in a single step. The reaction proceeds under neutral conditions and does not require external ligands or additives. The key to this reactivity is the unique activation mode of the rhenium carbonyl complex, which prefers to interact with heteroatoms in polar carbon–heteroatom bonds as well as nonpolar carbon–carbon unsaturated π bonds.

Phosphinoborane ligands impart unique reactivity to a rhenium carbonyl cation relative to simple phosphine complexes. Addition of either triethylborohydride or a platinum hydride (that can be formed from H2) forms a rhenium boroxycarbene. This carbene, which crystallizes as a dimer, disproportionates over a period of days to afford the starting cation and a structurally unprecedented boroxy(boroxymethyl)carbene, in which a new C−C bond has been formed between two reduced CO ligands. This product of C−C bond formation can be independently synthesized by addition of 2 equiv of hydride to the rhenium carbonyl cation.

Due to the versatility of the coordination modes of TPT with various metal ions under different reaction conditions, we concluded that a systematic synthetic study and structural determination of rhenium(I) tricarbonyl halide complexes of TPT would be most helpful to fully understand the complextion behavior of dinuclear rhenium(I) complexes.

Synthesis of N-heterocyclic carbene ..

We herein report the synthesis and structural and spectroscopic characterization of a series of dinuclear rhenium(I) carbonyl complexes of TPT under different reaction conditions.
