抄録

The ligand precursor xantsilH2 was prepared by selective dilithiation at the 4,5-positions of 9,9-dimethylxanthene with 2 equiv of n-BuLi/TMEDA followed by reaction with chlorodimethylsilane. Heating a solution of xantsilH2 with 0.4M equiv of Ru3(CO)12 in toluene to 120°C for 90min provided cis-Ru(xantsil)(CO)4. Three carbonyl ligands in cis-Ru(xantsil)(CO)4 can be replaced by a η6-toluene ligand to give Ru(xantsil)(CO)(η6-C6H5Me) in high yield. Substitution of the η6-toluene ligand with PCy3 afforded Ru(xantsil)(CO)(PCy3), which serves as a unique, high-performance catalyst.
