Transition metal-tin chemistry

Synthesis of new heterometallic complexes by tin–sulfur bond cleavage of pySSnPh3 (pySH = pyridine-2-thiol) at triruthenium and triosmium centres

“…Reagent-grade solvents were dried using appropriate drying agents and were freshly distilled prior to use by standard methods. Os 3 (CO) 12 and Ru 3 (CO) 12 were purchased from Strem Chemicals Inc. and used without further purification, [Os 3 (CO) 10 …”

“…There are few Os 3 Interestingly the Ru─Os(1) bond trans to the Ru─Sn bond is not significantly different to the Ru─Os(2) bond cis to it. 10 bond from such a species would directly afford 5, while for ruthenium a secondary transfer of the tin to the nitrogen bond atom followed by cluster core degradation could afford the labile Ru(CO) 2 (pyS)(SnPh 3 ) fragment which dimerises to form 1. (2)─Os (3) distance is found.…”

“…Transition metal-tin complexes have attracted considerable interest primarily because tin can be used to modify bimetallic catalysts, improving their reactivity and product selectivity in a variety of chemical transformations [1][2][3][4][5][6][7][8][9][10][11][12][13]. Further it has recently been found that the binding of metallic nanoparticles to oxide supports can be enhanced by the incorporation of tin [10][11][12][13][14].…”

Studies of the synthesis, structure, and reduction of trans-dichloro bis(2,3-dihydro-4- and 7-methylbenzo[b]thiophene)palladium(II) complexes

“…A useful review of possible mechanisms for the desulfurization of BT has been given by Gates et al (26). Reactions of la-c with CO/H,O A variety of metal complexes have been shown to catalyze the water gas shift (WGS) of CO/H20 to CO, and Hz under very moderate conditions (27)(28)(29)(30)(31)(32)(33)(34)(35)(36). A useful collation of recent work is given in ref.…”
