摘要

Each of the reducing radicals e,;, CO;, and (CH3) &OH cleaves bis (Bhydroxyethy1) trisulfide in aqueous solution to produce (2-hydroxyethy1) perthiyl (RSS-) radicals and 2- hydroxyethanethiol. The RSS. radical had h,,= 374 nm, cmru= 1630 f 50 M-'cm-l, and a second-order rate constant for dimerization 2kI2=(1.4 f 0.3) x lo9 Ml sl (2RSS--RSIR (12)). It is able to abstract H atoms from dihydroflavin adenine dinucleotide (FH,), but not from ...
