A novel and very simple to perform electrochemical approach for the synthesis of several N-cyanosulfilimines in good to excellent yields was established. This method provides access to biologically relevant sulfoximines by consecutive oxidation using electro-generated periodate. This route can be easily scaled-up to gram quantities. The S,N coupling is carried out at an inexpensive carbon anode by direct oxidation of sulfide. Therefore, the designed process is atom economic and represents a new “green route” for the synthesis of sulfilimines and sulfoximines.

A scalable process to the insecticide Isoclast manufactured by Dow AgroSciences LLC is described. The process involves the de novo construction of a fully elaborated pyridine sulfide using enamine-mediated cyclization followed by two efficient and inexpensive oxidations to introduce the sulfoximine.
PROCESS FOR THE PREPARATION OF CERTAIN SUBSTITUTED SULFILIMINES

Paragraph 0032-0033, (2014/06/24)
Cyano-substituted sulfilimines are produced efficiently and in high yield from the corresponding sulfides, cyanamide and hypochlorite by adding the sulfide to a solution of the cyanamide and hypochlorite in the presence of a nitrile solvent while maintaining the pH from about 8 to about 12.
METHODS OF PRODUCING SULFILIMINE COMPOUNDS
-
Paragraph 0039, (2013/08/28)
Methods of producing a sulfilimine compound, such as N-cyano-S-methyl-S-[1-(6-trifluoromethyl-3-pyridinyl)ethyl]sulfilimine or other substituted sulfilimine compound. The method includes combining a sulfide compound, cyanamide, a hypochlorite compound, and a base, and oxidizing the sulfide compound to form the sulfilimine compound. The sulfide compound may include a 2-trifluoromethyl-5-(1-substituted)alkyl-thiopyridine compound. The base may include sodium hydroxide. A buffer, such as a phosphate buffer, may, optionally, be used in the reaction.
