DCM is produced by treating either chloromethane or methane with chlorine gas at 400–500 °C. At these temperatures, both methane and chloromethane undergo a series of reactions producing progressively more chlorinated products.

Methyldichloroarsine, sometimes abbreviated "MD" and also known as methyl Dick, [1] is an organoarsenic compound with the formula CH 3 AsCl 2. This colourless volatile liquid is a highly toxic vesicant that has been used in chemical warfare .
Methyldichlorophosphine is produced by alkylation of phosphorus trichloride with methyl iodide followed by reduction of the resulting phosphonium salt with iron powder: [2] [3] CH 3 I + PCl 3 + AlCl 3 → [CH 3 PCl 3 ] + AlCl 3 I −
Methylphosphonyl dichloride is produced by oxidation of methyldichlorophosphine, with sulfuryl chloride: [3] CH 3 PCl 2 + SO 2 Cl 2 → CH 3 P(O)Cl 2 + SOCl 2. It can also be produced from a range of methylphosphonates (e.g. dimethyl methylphosphonate) via chlorination with thionyl chloride. Various amines catalyse this process. [4]
MAO serves multiple functions in the activation process. First it alkylates the metal-chloride pre-catalyst species giving Ti/Zr-methyl intermediates. Second, it abstracts a ligand from the methylated precatalysts, forming an electrophilic, coordinatively unsaturated catalysts that can undergo ethylene insertion.
Stock and Somieski completed the hydrolysis of dichlorosilane by putting the solution of H 2 SiCl 2 in benzene in brief contact with a large excess of water. [3] [5] A large-scale hydrolysis was done in a mixed ether/alkane solvent system at 0 °C, which gave a mixture of volatile and nonvolatile [H 2 SiO] n.
Paraquat (trivial name; / ˈ p ær ə k w ɒ t /), or N,N′-dimethyl-4,4′-bipyridinium dichloride (systematic name), also known as methyl viologen, is a toxic organic compound with the chemical formula [(C 6 H 7 N) 2]Cl 2. It is classified as a viologen, a family of redox-active heterocycles of similar structure. [5]
