Boron disulfide

Other reported binary boron sulfides include subvalent B12S, a black crystalline material prepared by a high-temperature reaction of amorphous boron with elemental sulfur, and BS, which has been studied spectroscopically in an electric discharge. A vapor-phase dimer, (BS)2, was identified, and a refractory condensed form of BS was reported from the reaction of elemental boron with sulfur at 1850°C and a pressure of 94 500 atmospheres. Boron disulfide, BS2, has been identified in the gas phase and appears to be the primary compound present in the vapor phase over diboron trisulfrde or elemental boron and sulfur. 

The monothioacetal is also stable to 12 N hydrochloric acid in acetone (used to remove an TV-triphenylmethyl group) and to hydrazine hydrate in refluxing ethanol (used to cleave an A -phthaloyl group). It is cleaved by boron trifluoride etherate in acetic acid, silver nitrate in ethanol, and tiifluoroacetic acid. The monothioacetal is oxidized to a disulfide by thiocyanogen, (SCN)2- ... 

Here are the correct names sulfur dioxide, carbon disulfide, boron trichloride, and bromine pentafluoride. 

Potassium chlorate (or other metal halogenate) intimately mixed with arsenic, carbon, phosphorus, sulfur or other readily oxidised materials gives friction-, impact- and heat-sensitive mixtures which may explode violently [1], When potassium chlorate is moistened with a solution of phosphorus in carbon disulfide, it eventually explodes as the solvent evaporates and oxidation proceeds [2], Boron bums in molten chlorate with dazzling brilliance [3]. Mixtures of the chlorate and finely powdered sulfur containing over 20% of the latter will explode under a hammer-blow [4],...

The disulfide fragment separating phosphorus and boron atoms was not replaced in 181 by chloral even after refluxing in benzene, evidence for high betaine stability. In methylene chloride, 175 reacts with 1,2-naphthoquinone, yielding phosphorane 182 [Eq. (135)]. This result is surprising, as one could have expected the formation of a betaine structure.

Covalent polymers with reversible properties arising from dynamic covalent bonds such as disulfide exchange reaction [47 9], transesterification [50,51], transetherification [52], and boronate ester formation [53] were reported without respect to DCC. These studies should involve DCLs in... 

Boron hydrides are soluble in carbon disulfide, diglyme and ethyl acetate. They react with water. 

Carbon disulfide gives an essentially quantitative yield of carbon tetrafluoride (4) and sulfur on reaction with sulfur tetrafluoride at 450 C in the presence of arsenic(III) fluoride as catalyst. At lower temperatures and with boron trifluoride as catalyst, bis(trifluoromethyl) polysulfides 5 and 6 are formed.205... 

Substitution of sulfur with sulfur tetrafluoride takes place in the presence of a catalyst. So carbon disulfide and sulfur tetrafluoride yield quantitatively carbon tetrafluoride with arse-nic(III) trifluoride, whereas, at lower temperatures, bis(trifluoromethyl) polysulfides are formed in the presence of boron trifluoride.21... 

Replacement of the carbonyl oxygen atom by sulfur may be effected by heating with phosphorus pentasulfide (49JCS2142), boron sulfide or silicon disulfide which gives high yields under mild conditions, as, for example, in the synthesis of 7-methoxy-2-methylchromene-4-thione (438) (69JCS(C)2192). Such compounds are more easily converted into their oximes or hydrazones than the oxygen compounds.
