An air oxidizable bimetallic palladium(II) catalyst for asymmetric allylic oxidation of olefins in acetic acid

Recent Advances in Enantioselective Pd-Catalyzed Allylic Substitution: From Design to Applications

“…They reported that cyclic olefins are oxidized to allylic acetates in good yields in up to 78% ee in acetic acid with molecular oxygen as oxidant and with the use of bidentate phosphorus or nitrogen ligands (DIOP or ( S )-METBOX). 685 …”

Use of CuO encapsulated in mesoporous silica SBA-15 as a recycled catalyst for allylic C–H bond oxidation of cyclic olefins at room temperature

“…8 The nature of the metal salt, perester oxidant, and reaction conditions including solvent and temperature are affected this reaction remarkably. [9][10][11][12][13][14][15][16][17] Allylic C-H bond oxidation have been studied by homogeneous catalysts such as selenium, [18][19][20][21][22][23][24] selenium dioxide, [18][19][20][21]23 diselenides 24 and pentauorobenzeneselenic acid [18][19][20][21][22][23][24] with different metals such as Hg(II), [25][26][27][28][29][30] Pd(II), [31][32][33][34][35][36][37] Pb(IV), 25 Cr(VI), 25,38,39 Co(III), 40,41 Co(II),…”

Toward Efficient Palladium‐Catalyzed Allylic CH Alkylation

“…Moreover the allyl coupling partner is constrained to aromatic allylic substrates in intermolecular cases, while some aliphalic allylic substrates have been employed for intramolecular alkylations. In addition, an evident but also very powerful extension of this methodology would be the development of a general, enantioselective protocol 15. Recent results have been very encouraging in that several possible strategies have proven successful for closely related transformations; for example, use of a chiral variant of benzoquinone,16 a chiral Lewis acid,17 or a chiral sulfoxide ligand18 illustrating that this goal can be reached in near future.…”
