Abstract
Treatment of the electronically unsaturated 4methylquinoline triosmium cluster hboxOs 3hboxCO 9upmu 3hboxupeta2hboxhboxC 9hboxH 5 hbox4MeNupmuhboxH 1 with tetramethylthiourea in refluxing cyclohexane at 81°C gave hboxOs 3hboxCO 8upmuhboxupeta2hboxC 9hboxH 5 hbox4MeNupeta2hboxSChboxNMe 2hboxNCH 2hboxMeupmu hboxH 2 2 and hboxOs 3hboxCO 9upmuhboxupeta2hboxC 9hboxH 5hbox4MeNupeta1hboxSChboxNMe 2 2upmuhboxH 3 In contrast a similar reaction of the corresponding quinoline compound hboxOs 3hboxCO 9upmu 3hboxupeta2hboxC 9hboxH 6hboxNupmuhboxH 4 with tetramethylthiourea afforded hboxOs 3hboxCO 9upmuhboxupeta2hboxC 9hboxH 6hboxNupeta1hboxSCNMe 2 2upmuhboxH 5 as the only product Compound 2 contains a cyclometallated tetramethylthiourea ligand which is chelating at the rear osmium atom and a quinolyl ligand coordinated to the Os3 triangle via the nitrogen lone pair and the C8 atom of the carbocyclic ring In 3 and 5 the tetramethylthiourea ligand is coordinated at an equatorial site of the osmium atom which is also bound to the carbon atom of the quinolyl ligand Compounds 3 and 5 react with PPh3 at room temperature to give the previously reported phosphine substituted products hboxOs 3hboxCO 9upmu hboxupeta2hboxC 9hboxH 5hbox4MeNPPh 3upmuhboxH 6 and hboxOs 3hboxCO 9upmu hboxupeta2hboxC 9hboxH 6hboxNPPh 3upmuhboxH 7 by the displacement of the tetramethylthiourea ligandWe gratefully acknowledge the Ministry of Science and Technology Government of the People’s Republic of Bangladesh for financial assistance NB acknowledges ShereBangla Agricultural University Dhaka for study leave ER acknowledges the US Department of Energy for support
