Thermal decomposition of methyl xanthates is similar to the pyrolysis of acetates for the formation of the double bond. Olefins are obtained from primary, secondary, and tertiary alcohols without extensive isomerization or structural rearrangement. The other products of the pyrolysis of the methyl xanthates are methyl mercaptan and carbon oxy-sulfide. The xanthates prepared from primary alcohols are more difficult to decompose than those prepared from secondary and tertiary alcohols. Over-all yields of 22-51% have been obtained for a number of tertiary alkyl derivatives of ethylene. Originally the xanthates were made by successive treatment of the alcohol with sodium or potassium, carbon disulfide, and methyl iodide. In a modification of this procedure sodium... 

Hydrodesulfurization of thiophene Cr-M impr. with H2S/H2 The activity of the presulfided catalyst was very high and greater than the unsulfided catalyst, but decreased slowly with time. Activity was postulated to arise from chromium (oxy) sulfides. 59... 

There are different fashions how to induce water removal in condensation reactions. By simply heating amino acids with or without potent agents of condensations such as hydrogen cyanide, HC=N, cyan amide, N=C-NH2, and carbon-oxy-sulfide COS, oligomers and polymers, called proteinoids, readily formed. The detection of enzymatic activities in these polymeric proteinoids was unsuccessful except for about ten degrading enzymatic activities. Synthetic activities that build up molecules, for instance, kinase, ligase, and polymerase, were not detectable. The disadvantage of these mixtures of proteinoids is that they do not exhibit a distinct structure or a function. 

Dithiazine (86) gives the j -thiolactam (87) after concerted thermal elimination of carbon oxy-sulfide followed by further rearrangement of the ensuing 1,3-thiazetidine (Scheme 4) <84CB2205>. 

These chiral allylic cyclic carbonates are also capable of reacting with carbon, oxygen, or sulfur nucleophiles to provide products whose regio- and diastereoselectivities depend on the nature of the nucleophile. The reaction of 551 with phenol in the presence of palladium(O) and triethylamine provides in 79% yield 555, whereas similar reaction with sodium benzene-sulfinate furnishes the ( )-allylic alcohol 556 in 80% yield. However, sodium thiophenoxide, under conditions that do not lead to catalyst poisoning, attacks proximal to the oxygen atom with inversion to afford the threo-P-hy oxy sulfide 557 in 74% yield. This reaction is not observed in the absence of a palladium catalyst [181] (Scheme 123). 

Modern CT systems use solid state detectors in general. Each detector element consists of a radiation-sensitive solid-state material (such as cadmium tungstate, gadolinium-oxide or gadolinium oxi-sulfide with suitable dopings), which converts the absorbed X-rays into vis-...
