This work demonstrated the photoinduced hydroxytrifluoromethylation of aliphaticalkenes catalysed by Mn(acac)3. The synthesis uses an inexpensive catalyst under mild reaction conditions, and exhibits a wide substrate scope and excellent functional group tolerance.

[reaction: see text]Transannular macrocyclizations via intramolecular B-alkyl Suzuki reactions are described. Regioselective terminal olefin hydroboration with 9-BBN followed by Pd(0)-catalyzed Suzuki reaction in the presence of a base such as TlOEt at high dilution generates macrocycles with a high degree of control over olefin geometry with isomerically pure E or Z vinyl iodide substrates.
