Scheme 7. Comparison of original photosplicing reaction with the thiol-ene-photosplicing reaction and Suzuki reaction. (A) Original photosplicing reaction in two steps starting from TsCl and benzylamine. (B) Suzuki reaction with critical raw materials for comparison. (C) Thiol-ene-photosplicing starting from phenylthiol and styrene. Two different examples to give biphenyl 2a and biphenyl 2e.
