In the title compound, [Cu(CH3CN)4](C2HO4)·0.5C2H2O4·0.5CH3CN, the CuI ion is coordinated by the N atoms of four acetonitrile ligands in a slightly distorted tetrahedral environment. The oxalic acid molecule lies across an inversion center. The ace

The dinuclear molecule of the title compound, [Cu2(C2O4)(C18H15P)4]·2CH2Cl2, lies across an inversion center with a strictly planar bridging oxalate ligand coordinating two CuI ions via two pairs of O atoms. Two triphenylphosphine ligands also coord

Copper(I) and gold(I) thiolates were synthesized in quantitative or near-quantitative yield by the direct reaction of aqueous Cu(NO3)2 or HAuCl4 with aqueous thiols HSCH2CH2OH and HSCH2CH2OCH2CH2OH. The resulting highly insoluble thiolates had spectr

Carboranes are boron-rich molecules that can be functionalized through metal-catalyzed cross-coupling. Here, for the first time, we report the use of bromo-carboranes in palladium-catalyzed cross-coupling for efficient B-N, B-O, and unprecedented B-C
