COMPOSITION FOR TIN-SILVER ALLOY ELECTROPLATING COMPRISING A COMPLEXING AGENT

An aqueous composition comprising (a) metal ions comprising or consisting of tin ions and silver ions and (b) at least one complexing agent of formula (C11): RC12-XC11-RC11 and their salts, wherein XC11 is selected from (a) a divalent 5 or 6 membered aromatic N-heterocyclic group comprising (i) a single N atom; or (ii) a first N atom and a second heteroatom selected from N and S, wherein the first N atom and the second heteroatom are separated by at least one C atom; or (iii) a triazole or thiadiazole; (b) a divalent 6 membered aromatic carbocyclic group; (c) a divalent 5 or 6 membered aliphatic N-heterocyclic group comprising one N atom and optionally a second heteroatom selected from N and O; all of which may be unsubstituted or substituted by one or more OH or one or more RC14; RC11 is selected from (a) -XC12-S [-XC13-DC11]n-RC13, (b), and (c); RC12 is selected from RC11, XC11-RC11, H, OH, NRC142, C1 to C10 alkyl, and C1 to C10 alkoxy; XC12 is a chemical bond or a linear, branched or cyclic C1-C6 alkanediyl, which may be unsubstituted or substituted by OH, with the proviso that if XC11 is (a) a divalent 5 or 6 membered aromatic N-heterocyclic group and (b) RC13 is substituted by one OH and (c) RC12 is not RC11, then XC12 is a chemical bond; XC13 is a linear, branched or cyclic C1-C6 alkanediyl, which may be unsubstituted or substituted by OH; XC14 is a chemical bond or a linear or branched C1-C4 alkanediyl; DC11 is selected from S and O; RC13 is selected from (a) a linear, branched or cyclic C1-C6 alkyl, which may be unsubstituted or substituted by one or more OH, (b) if XC11 is not an aromatic carbocyclic group, Ph, XC14- Ph, with Ph=phenyl, and (c) a C2 to C4 polyoxyalkylene group; with the proviso that if XC11 is a divalent 5 or 6 membered aromatic N-heterocyclic group, then RC13 is unsubstituted or substituted by one OH with the exception that if XC11 is a divalent 5 or 6 membered aromatic N-heterocyclic group comprising a first N atom and a second heteroatom selected from N, then RC13 is unsubstituted. RC14 is selected from H and a linear, branched or cyclic C1-C6 alkyl; n is 0 or an integer of from 1 to 5.

Oligomerisation reactions of beta substituted thiols in water

Beta substituted thiols and various derivatives containing the HX-C-C-SH motif oligomerise in water, preferably in the presence of a carbonate salt. The reaction yields oligomers consisting of one thiol end group, a thiaethylene backbone and an additional terminal group corresponding to the starting material used. Mechanistic studies, as well as the scope of substrates and products of these new promising condensation processes, are presented. In addition, strong nucleophiles were also reacted with mercaptoethanol under simple reaction conditions, leading to the selective formation of more complex molecules.

Synthesis of dithioetherdithiols, potential technetium complexing agents

The following dithioetherdithiols : 2,10-dimethyl-4,8-dithiaundecane-2,10-dithiol 1, 5-butyl-3,7-dithianonane-1,9-dithiol 2 and 4,4,6,6-tetramethyl-3,7-dithianonane-1,9-dithiol 3 have been synthesized.These compounds are very attractive as potential precu

Tri-n-butyltin Hydride: A Selective Reducing Agent for 1,3-Dithiolanes

Tri-n-butyltin hydride has been found to be an effective and selective agent for complete or partial desulfurization of 1,3 dithiolanes 1.The reaction of 1 with 4 equiv of tri-n-butyltin hydride in the presence of 2,2'-azobis(isobutyronitrile) results in complete desulfurization, giving hydrocarbons 2 in good yield, ethane and bis(tri-n-butyltin) sulfide.Two equivalents of hydride specifically cleave the two geminal C-S bonds in 1 to give hydrocarbons 2 and bis(tri-n-butylstannyl) ethanedithiolate.One equivalent of tri-n-butyltin hydride reduces 1 quantitatively to the β-ethyl tri-n-butyltin sulfides 11.
