Abstract: Abstract Exquisite control of catalytic metathesis reactivity is possible through ligand‐based variation of ruthenium carbene complexes. Sterically hindered alkenes, however, remain a generally recalcitrant class of substrates for intermolecular cross‐metathesis. Allylic chalcogenides (sulfides and selenides)… read more here.

Abstract: A visible-light-mediated radical allylation of primary amine-derived Katritzky salts with allylic sulfones via C(sp3)–N bond activation is reported, furnishing the corresponding alkenes in satisfactory yields. This mild protocol provides an efficient strategy for site-specific C(sp3)–C(sp3)… read more here.

DOI: 10.1039/d1qo00344e
Abstract: The first example of the synthesis of allylic sulfones through synergistic photoredox and tertiary amine catalysis, starting from MBH acetates, DABCO·(SO2)2 and 4-substituted Hantzsch esters or potassium alkyltrifluoroborates via a radical pathway, is reported. read more here.
