Mechanism of a Redox Coupling of Seleninic Acid with Thiol Mohannad Abdo Spencer Knapp 10.1021/jo300156x.s001 https://acs.figshare.com/articles/journal_contribution/Mechanism_of_a_Redox_Coupling_of_Seleninic_Acid_with_Thiol/2533381 Equimolar quantities of 2-ethoxyethaneseleninic acid and <i>p</i>-thiocresol react rapidly in dichloromethane solution to give the selenosulfide along with disulfide, diselenide, and two products oxidized at sulfur, the thiosulfonate and the selenosulfonate. The latter two are new for this sort of coupling; their formation may be the result of an early thioseleninate to selenosulfinate isomerization. A radical chain mechanism is proposed to account for all five products, as well as their relative amounts. 2016-02-21 15:20:55 selenosulfonate chain mechanism Mechanism Redox acid ethoxyethaneseleninic Seleninic latter thioseleninate selenosulfinate isomerization disulfide sulfur thiosulfonate diselenide formation dichloromethane solution ThiolEquimolar quantities selenosulfide quantity
