摘要：

The dimetallacyclic complex H2C(Me2SiC equivalent to CAuPMe2)(2)CH2 has been synthesized, in which the two gold centers are bridged by the diphosphine dmpme (= bis(dimethylphosphino)methane) and a diethynyl ligand providing "full support" for the possible transannular Au-Au contact (3). This compound and its "semi-" and "unsupported" analogues (2, 1) have been characterized by NMR spectroscopy and elemental analysis. The monomeric nature of complex 3 in solution has been established using diffusion coefficients measured by DOSY-NMR spectroscopy and comparing the data with those of complexes 1 and 2 as references.
