A series where a compound with two of this functional group is added to a carbonyl and treated with Raney (*) Nickel eliminates the carbonyl.
In the Saville reaction, a nitrosyl bonded to one of these compounds is replaced, while a sodium variety reacts with a zinc compound in the Herz reaction. A series where a compound with two of this functional group is added to a carbonyl and treated with Raney (*) Nickel eliminates the carbonyl. Cysteine is the only amino acid belonging to this class of compounds making it important in forming tertiary structures like disulfide bridges. Traditionally referred to as mercaptans, for 10 points, identify this class of molecules which give skunks and onions their foul smell and contain hydrogen-sulfur functional groups.
In the Saville reaction, a nitrosyl bonded to one of these compounds is replaced, while a sodium variety reacts with a zinc compound in the Herz reaction.
