摘要:
Displacement of tetrahydrothiophene (tht) from [Au(ylide)(tht)ClO4 (ylide=CH2PPh3, CH2PPh2Me, CH2PPhMe2, CHPhPPh3, CHMePPh3 or CH2AsPh3) by other neutral or anionic ligands leads to the mono- and dinuclear cationic complexes [Au(ylide)L]ClO4 (L=SbPh3 or phen) or [{Au(ylide)}2(L-L)]ClO4 (L-L=dppm or dpam), complexes with tetracarbonylcobaltate as ligand [Au(ylide){Co(CO)4}] or acetylide complexes [Au(ylide)(C=CR)] (R=Ph or (t)Bu). The structure of [Au(CH2PPhMe2)(phen)]ClO4 was established by single-crystal X-ray diffraction studies.
