Sodium thiocarboxylate

A few chalcogenocarboxylato complexes of titanium are known, R2Ti(RCOS) [8,42] and Cp2Ti(RCOS)2 [Cp =(CH3)C5H4] [7], which can be synthesized by reacting R2TiCl (Cp or indenyl) with sodium thiocarboxylate or Cp2TiCl2 with sodium thiocarboxylate, respectively. Their detailed structures are not yet fully known. [Pg.26]

Bis(thiocarboxylato) niobium 18Nb(RCOS)2 [207] and bis(r] -cyclopenta-di-enyl)bis(thiobenzoato)niobium 19 [110] have been synthesized by stoichiometric reactions of NbCl2 with sodium thiocarboxylates and of Nb(Cp)2X2 (X=C1, Br, I) with thallium thiobenzoate, respectively. The structure of 19 is considered to be analogous to the tantalum complex 20, in which the thiocar-boxylato ligands are monodentate through the sulfur atom [110]. [Pg.27]

Sodium thiocarboxylates readily react with zinc salts such as ZnCl2 or Zn(N03)2 in aqueous solution to give the thiocarboxylato zinc complexes 64, possessing two crystallizing H2O molecules [271]. Reaction of thiocarboxylic acid with diethyl zinc in the presence of lutidine has been found to give the adduct Zn(RCOS)2(L)2 (L=3,5-lutidine) 65 in good yields [249]. Anionic thiocarboxylato complexes 66 (M=Zn) have also been isolated from the reaction of... [Pg.37]

Coupling sodium tellurocarboxylates with R SiCl gives the unstable silyl derivative which isomerizes to the more thermodynamically stable RC(Te)OSiR 3 through a facile rearrangement that can be readily followed by 13C NMR spectroscopy. This contrasts with the reaction of alkali metal thiocarboxylates which give the O-silyl ester directly. There is no evidence for the S-silyl intermediate101. [Pg.1889]

Prop-2-ynyl)-5-(trifluoromethyl)-l, 3,4-thiadiazol-2(3//)-one (19) reacts with nucleophiles (ammonia, pyrrolidine, or potassium methylthiolate) with formation of 6-methylene-2-(trifluo-romethyl)-5,6-dihydro-4//-l,3,4-thiadiazine-4-carboxamides 20a, b or S-methyl 6-mcthylene-2-(trifluoromethyl)-5,6-dihydro-4//-l,3,4-thiadiazine-4-thiocarboxylate (20c).82 The action of aqueous sodium hydroxide on 19 gives rise to the 4//-1,3,4-thiadiazine 20d, which also bears an exocyclic methylene group.82... [Pg.509]

Acylation of alkylidenetriphenylphosphoranes by thiocarboxylic 5-ethyl esters 456 The reactions are carried out in a Schlenk tube, as above. To a boiling solution (which need not be filtered) of a salt-free alkylidenephosphorane (0.022 mole) in anhydrous toluene is added an 5-ethyl thiocarboxylate (0.02 mole), and the mixture is boiled for 18 h. The phosphonium thiolate, that is initially precipitated as an oil, gradually redissolves. If an unfiltered ylide solution was used, the reaction solution must be filtered hot at this stage to remove sodium... [Pg.925]
