M. Akita et al., Synthesis and dehydrative condensation of monomeric hydroxoruthenium complexes with hydrotris(3,5-diisopropylpyrazolyl)borate ligand, Tp(2)(iPr)Ru(L-2)-OH (L-2 = dppe, bipy), INORG CHEM, 40(1), 2001, pp. 169
Monomeric neutral hydroxoruthenium complexes, Tp(2)(iPr)RuOH(L-2) (L-2 = dp
pe, bipy), are prepared by deprotonation of aquo complexes, and it is confi
rmed that dehydrative condensation reaction of the hydroxo complexes with c
arboxylic acids involves protonation of hydroxo ligand followed by replacem
ent of the resultant aquo ligand by the nucleophile.
