A A light-on-off experiment ruled out the involvement of radical chain mechanisms B The effect of light intensity to the reaction rate. C Trapping of the resulting benzyl radical using benzalmalononitrile. D A deuterium labeling experiment to support the process of migration. E Control expriments to confirm the generation of key intermediates. F Substrates lack the ability to migrate failed to produce the product. G A complementary solution to cleave the C(sp2)-C(sp3) bonds.
