Irradiation of S-alkyl 3-oxobutanethioate (1) in benzene or ethanol yielded the disulfide 2.Irradiation of S-alkyl α-bromothioacetate also gave the disulfide 2.The photochemical reaction of the 3-oxobutanethioate 1 involves the Norrish Type I reaction followed by rapid fragmentation of the radical CH2COSR to the thiyl radical 5.
PHOTOREACTION OF S-BUTYL 3-METHOXY-2-BUTENETHIOATE. COMPETITIVE 1,5-METHYL MIGRATION AND O-DEMETHYLATION.

, p. 3343 - 3344 (1984)
Irradiation of S-butyl (Z)-3-methoxy-2-butenethioate (1Z) gave the 1,5-methyl migration product 2 and the O-demethylation product 3. The photo-1,5-methyl migration occurred competitively with the O-demethylation from the pi , pi * excited triplet state of 1Z. The migration product 2 underwent the secondary photoreaction to 3 in a nondegassed benzene solution.
