The current status of saccharin is that it is allowed in most countries, and countries such as Canada have lifted their previous ban of it as a food additive. This condensing reagent was easily prepared by reacting saccharin and trichloromethyl chloroformate in 2:1 molar ratio under refluxing toluene as shown in Scheme 109.135. However, saccharin and its derivatives offer other opportunities and challenges to the synthetic chemists and biologist for the appropriate use of the same in different way, and we believe that these opportunities will never end because these catalysts will indeed form a huge source for catalytic strategies.

Furthermore, many alkenes can take two geometric forms: We will have more to say about the subject of, Alkanes, alkenes, and alkynes are all classified as, When the carbon of an alkane is bonded to one or more halogens, the group is referred to as a, Note that the definition of a phenol states that the hydroxyl oxygen must be, The deprotonated forms of alcohols, phenols, and thiols are called, One of the most important properties of amines is that they are basic, and are readily protonated to form, Do not be confused by how the terms primary, secondary, and tertiary are applied to alcohols and amines the definitions are different.
