The novel tetrahydroborate complexes (PCy3)2Cu(BH4), (np3)Cu(BH4) [np3 = tris(2-(diphenylphosphino)ethyl)amine] and (etp3)Cu(BH4) [etp3 = 1,1,1-tris((diphenylphosphino)ethyl)ethane] have been synthesized and characterized. The reactivity of these compounds and of other copper(I) tetrahydroborates, (PPh3)2Cu(BH4), (triphos)Cu(BH4) [triphos = 1,1,1-tris((diphenylphosphino)methyl)ethane], and (PMePh2)3Cu(BH4), toward CO2 and COS have been investigated. The latter triatomic molecules are reduced under very mild conditions to give metalloformate or metallothioformate derivatives. The bonding mode of the BH4- ligand, i.e. unidentate or bidentate, has been found to influence the rate of the reactions. The reactivity of the formate complex (triphos)Cu(O2CH) has been investigated in some detail. The latter compound has been studied by X-ray analysis. Crystal data: orthorhombic, space group Pn21a, a = 20.901 (8) ?, b = 17.136 (6) ?, c = 10.162 (4) ?, Z = 4, R, Rw = 0.055, 0.054 for 2267 reflections having I ≥ 3σ(I). The bonding mode of the formate group was shown to be through one oxygen atom.
