Tri­methyl 4,4′,4′′-(ethene-1,1,2-tri­yl)tribenzoate

The tandem in situ double Suzuki coupling reaction of a diborated ethyl­ene compound containing electron-withdrawing aromatic ester groups was studied. The major product is derived from the Suzuki coupling involving the boryl group and an aryl­iodide derivative followed by preferential protodeboronation of the second boryl ligand.

Bis(3-methyl-1-propyl-1H-imidazol-3-ium) bis­(4,6-disulfanidyl-4,6-disulfanyl­idene-1,2,3,5,4,6-tetra­thia­diphosphinane-κ3S2,S4,S6)nickel

The title salt, [PMIM]2[Ni(P2S8)2] (PMIM = 3-methyl-1-propyl-1H-imidazol-3-ium), was prepared from the elements in the ionic liquid [PMIM]CF3SO3. The structure consists of ordered anions and one ordered PMIM cation. The disordered PMIM cation is found in two orientations that refine to occupancies of roughly 0.80 and 0.20. The isolation of the title compound indicates that well behaved crystals can be obtained from direct reaction of the elements in ionic liquids with propyl chains that might otherwise be considered too prone to poor crystallization.
