Molecular A-frames. Reversible addition of diazoalkanes to dinuclear metal centers and the formation of [Rh2(μ-N2CRCO2Et)(CO)2(dppm) 2] (R = H, CO2Et)

Ethyl diazoacetate and diethyl diazomalonate react with the A-frame precursor complex [Rh2(μ-H)2-(CO)2(dppm)2] where dppm = bis(diphenylphosphino)methane resulting in the elimination of H2 and formation of 1:1 adducts. These new complexes are formulated as the A-frame molecules [Rh2(μ-N2CHCO2Et)(CO)2(dppm) 2] and [Rh2(μ-N2C(CO2Et)2)(CO) 2(dppm)2] based on elemental analyses, spectroscopic data, and subsequent reaction chemistry. On photolysis or thermolysis, these adducts do not eliminate N2 but rather dissociate the intact diazoalkane molecule. The ethyl diazoacetate adduct is reversibly protonated to form [Rh2(μ-N2CH2CO2Et)(CO) 2(dppm)2]BF4 on treatment with HBF4·OEt2 whereas the diethyl diazomalonate derivative reacts with this same protic source to effect loss of the diazoalkane and formation of [Rh2(μ-H)(CO)2(dppm)2]BF4. The A-frame complex [Rh2(μ-p-N2C6H4NO 2)(CO)2(dppm)2]PF6 is prepared by the reaction of (p-N2C6H4NO2)PF6 with the A-frame precursor complex.
