A sunple method for the detemunatlon of 2-thlohydantoms based on the mductlon of the lodme-azlde reactlon was developed The consumption of lodme IS proportional to the amount of the Inductor The mducmg properties of different compounds (S2-) were estunated from the mductlon coefficient <rI]/[Sj) whi

The lodme-azlde reactIon Induced by sulphutt -II) compounds was apphed to the determmatlon of cyamde ions m aqueous solution The method IS based on the converSion of cyamde by an excess of tetratluonate mto tluosulphate and thmcyanate followed by the determmahon of the products by the mdme-azlde reaction The method allows the determmation of 0 05 pg of cyanide m a 5-ml sample

have demonstrated that reductive methylation with labeled formaldehyde and NaCNBH, provides a simple method for specifically labeling the amino groups of proteins using extremely mild reaction conditions. However, cyanide, which is one of the products of the reaction, reduces labeling efficiency by
Aromatic aldehydes or ketones which have electron-withdrawing groups on the benzene ring were selectively reduced to the corresponding alcohols in good yields by sodium hydrogentelluride; common aldehydes such as benzaldehyde and tolualdehyde were inert.
