Sulfochlorination of Paraffins. The sulfonation of paraffins using a mixture of sulfur dioxide and chlorine in the presence of light has been around since the 1930s and is known as the Reed reaction (123). This process is made possible by the use of free-radical chemistry and has had limited use in the United States. Other countries have had active research into process optimization (124,125). 

Simultaneous treatment of an alkane with sulfur dioxide and chlorine affords a sulfonyl chloride, eg, hexylsulfonyl chloride [14532-24-2] and is referred to as chlorosulfonation or the Reed reaction (247,248). 

The first sulfonate was prepared from paraffin and SO2CI2 by the Reed reaction (eq. 11) (58,59) ... 

The chlorosulfonation of organic molecules with chlorine and sulfur dioxide is called the Reed reaction In scope and range of products obtained, the reaction is similar to 14-1. The mechanism is also similar, except that there are two additional main propagation steps ... 

The reaction of sulfur dioxide and chlorine with paraffin hydrocarbons to yield alkane sulfonyl chlorides (RH + S02 + Cl2 - RS02C1 + HC1) (the Reed reaction) was patented in 1939.221 This reaction has usually been run in the liquid phase under strong illumination with short wavelength visible or ultraviolet light.107,218 267... 

Alkanesulfonyl chlorides are prepared in good yields by the photoreaction of sulfur dioxide and chlorine with saturated hydrocarbons.89 157 158 This sulfochlorination, known as the Reed reaction,159 presumably proceeds by a free-radical mechanism 158 160... 

Photolysis of alkane/S02 mixtures leads to the formation of alkylsulfonic acids,the Hostapon process utilizing SOdOilhvP It is curious that this reaction seems to be so efficient, given the low e for alkane and SO2 at the wavelengths used, and an efficient chain reaction is presumably involved. The Reed reaction uses SO2/CI2/I11 to convert alkanes to the corresponding sulfonyl chlorides. Alkanes also react with SO3 to give alkyl sulfonates, sulfones and sulfates. ... 

The chlorosulfonation of organic molecules can be achieved by treatment with a mixture of sulfur dioxide and chlorine in the presence of ultraviolet light (the Reed reaction) this is a free radical process (Scheme 22). In this process, the liberated chlorine radical can then continue the radical chain reaction. 

Sulfonyl chlorides (51) may also be obtained by heating the sulfonic acid or its sodium salt with thionyl chloride or phosphorus pentachloride (Scheme 31). The reaction with thionyl chloride is catalysed by the addition of a few drops of DMF. The chlorosulfonation of organic compounds may also be achieved by reaction with sulfur dioxide and chlorine this is an important industrial process (the Reed reaction) (Scheme 32).

Reed reaction. Photochemical sulfonation of paraffins and cycloparaffins by sulfur dioxide and chlorine under irradiation with UV light. 

Secondary alkane sulphonates, also called paraffinsulphonates, are generated by sulphochlorination or by sulphoxidation of linear paraffins. Sulphochlorination (Reed reaction) means introduction of the SO2-CI moiety in a paraffin molecule by action of CI2 and SO2 under UV-irradiation followed by hydrolysis and neutralization with NaOH. Reaction of SO2 and O2 with n-paraffins under UV light is called sulphoxidation.
