Carbon tetrachloride, also known by many other names (such as carbon tet for short and tetrachloromethane, also recognised by the IUPAC), is a chemical compound with the chemical formula CCl 4. It is a non-flammable, dense, colourless liquid with a "sweet" chloroform-like odour that can be detected at low levels.
1,1,1,3,3,3-Hexachloropropane is a compound of chlorine, hydrogen, and carbon, with chemical formula C 3 Cl 6 H 2, specifically Cl 3 C−CH 2 −CCl 3. Its molecule can be described as that of propane with chlorine atoms substituted for the six hydrogen atoms on the extremal carbons.
Carbon tetrachloride interestingly enough, only undergoes the reaction a single time with chloroform being inert to the reaction conditions. When a halide atom is found in the ester chain off of the phosphorus atom, isomerization to the corresponding Arbuzov product has been known without addition of an alkyl halide.
The Appel reaction is an organic reaction that converts an alcohol into an alkyl chloride using triphenylphosphine and carbon tetrachloride. [1] The use of carbon tetrabromide or bromine as a halide source will yield alkyl bromides, whereas using carbon tetraiodide, methyl iodide or iodine gives alkyl iodides. The reaction is credited to and ...
By the reaction of carbon tetrachloride and hafnium oxide at above 450 °C; [5] [6] HfO 2 + 2 CCl 4 → HfCl 4 + 2 COCl 2. Chlorination of a mixture of HfO 2 and carbon above 600 °C using chlorine gas or sulfur monochloride: [7] [8] HfO 2 + 2 Cl 2 + C → HfCl 4 + CO 2. Chlorination of hafnium carbide above 250 °C. [9]
In addition, a variety of simple chlorinated hydrocarbons including dichloromethane, chloroform, and carbon tetrachloride have been isolated from marine algae. [7] A majority of the chloromethane in the environment is produced naturally by biological decomposition, forest fires, and volcanoes.
The Zincke–Suhl reaction is a special case of a Friedel-Crafts alkylation and was first described by Theodor Zincke and Suhl in 1906. [1] [2] [3] Unlike the traditional Friedel-Crafts reaction, the reduction of the phenyl ring leads to a higher energy final product that can be used as starting material in the dienol–benzene rearrangement, among other reactions.
Hexachloroethane (perchloroethane) is an organochlorine compound with the chemical formula (CCl 3) 2.It is a white or colorless solid at room temperature with a camphor-like odor. [3]
