Syntheses of very soluble alkylated bicyclic guanidinate ligands and structural characterization of a dipalladium paddlewheel
摘要:
Fool-proof syntheses of two highly soluble tetraalkylated bicyclic guanidinates which are characterized by the NC(N)N core are reported along with the structures of the corresponding hydrochlorides. The compound with alkyl = methyl was used to prepare a paddlewheel species with a Pd-2(4+) core devoid of a strong metal-metal bond but potentially useful as precursor to a rare single bonded Pd-2(6+) species. The Pd1...Pd2 separation is only 2.5488(12) angstrom and the local coordination for each of the d(8) Pd(II) atoms is square planar. Published by Elsevier Ltd.
