The rate constants for the 1,3-and 1,Mgmatropic hydrogen shifts of the phot&Fries rearranged intermediates of phenyl acetate produced by laser flash photolysis at 266 nm were directly measured in several solvents. The rate constant for the 1,3hydrogen shift (3.6 s-l) was faster than that for the l&s

Products derived from the homolysis of the aromatic C-I bond of ortho-iodobenzophenones by photolysis or tributyltin radicals indicate 1,5-hydrogen migration. The reactions include iodine migration, hydrogen abstraction and arylation.
