Irradiation of <I>S</I>-butyl (<I>Z</I>)-3-methoxy-2-butenethioate (<B>1Z</B>) gave the 1,5-methyl migration product <B>2</B> and the <I>O</I>-demethylation product <B>3</B>. The photo-1,5-methyl migration occured competitively with the <I>O</I>-demethylation from the π, π<SUP>*</SUP> excited triplet state of <B>1Z</B>. The migration product <B>2</B> underwent the secondary photoreaction to <B>3</B> in a nondegassed benzene solution.
