Synthetic Route of 37366-09-9. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer
Reaction of the ruthenium(IV) chloro-bridged dimer <2> 1 with a range of alkane- and arene-thiols in CH2Cl2 resulted in the formation of the simple, bridge-cleaved adducts (R=Et 2, Me 3, iPr 4, tBu 5 or Ph 6).Reaction of 1 with an excess of thiol in methanol gave doubly thiolate-bridged compounds <2> (R=Et 7, Ph 12 or C6F5 13) each of which exists as two diastereoisomers but as a single geometrical isomer.In the case of 7 and 12 separation of the two diastereomeric forms proved possible because of their remarkably different solubilities in methanol, and their kinetic inertness.Reactions of 2 and 3 with 1 gave the mixed-bridge chloro/thiolato complexes <2(mu-Cl)(mu-SR)> (R=Me 9 or Et 8).The unusual stereochemistry of these compounds is evident from analysis of their variable-temperature 1H NMR spectra.The crystal structure of 8 has been determined.Reaction of 1 with H2S in CH2Cl2 proceeds via the H2S adduct 10, which rapidly reacts with further 1 with accompanying loss of HCl to give the singly SH-bridged complex <2(mu-Cl)(mu-SH)> 11.Reaction of the EtSH compound 2 with a range of Ru(II) and Rh(III)-containing compounds enabled the isolation of a number of unusual mixed-valence and mixed-metal complexes containing one or two bridging ethanethiolate ligands.The ruthenium(IV)-rhodium(III) compounds <(eta3:eta3-C10H16)ClRu(mu-Cl)(mu-SEt)RhCl(eta5-C5Me5)> and <(eta3:eta3-C10H16)ClRu(mu-SEt)2RhCl2(PMe2Ph)2> have been characterized by X-ray crystallography.
