LC spectra following separate addition of 1 eq of 1 and 2 to 2.1 eq of GSH; peak mass determined by MS; a) 1-(GSH)2 and GSH; b) 2-(GSH)2 and GSH; c) LC/MS spectra of 1: 1 mixture of 2 and GSH to deliver mono-adduct 2-(GSH) as the major product and bis-product 2-(GSH)2 as the minor product based on the MS.
