Diastereoselective diazenyl formation: the key for manganese-catalysed alcohol conversion into (E)-alkenes

“…16 Definitively, these are just a few instances amongst the plethora of organic transformations catalysed by manganese that have been reported in the last lustrum. [17][18][19][20][21][22][23][24][25][26] Encouraged by our interests in the unravelling of the mechanistic aspects in the catalytic chemistry of manganese, [27][28][29][30] the recent work by Milstein et al, 31 reporting for first-time a manganese-catalysed coupling of alcohols and hydrazone to form alkenes, caught our attention. As an alternative to the classical approaches for the synthesis of olefins from carbonyl compounds (such as Wittig, 32 Peterson, 33 or Julia 34 olefinations), Milstein and co-workers offer an unprecedented base-and waste-free procedure for the direct transformation of alcohols into alkenes.…”

Recent Advances on Catalytic Osmium‐Free Olefin syn‐Dihydroxylation

“…Then addition of H 2 O 2 generates the active grafted [(tmtacn)Mn III (µ‐O)(µ‐RCOO) 2 Mn III (tmtacn)] 2+ species. [ 48 ] Careful spectroscopic analyses confirmed that the Mn III /Mn III dimer was fixed onto the acid‐functionalized silica surface. This in situ anchored catalyst was then evaluated in the oxidation of cyclooctene.…”

Metal Catalyzed Oxidation Reactions of Alkenes Using Eco-Friendly Oxidants

“…In past years, scientists utilized various metals such as Pd, Mn, Mo, Se, Fe, etc. for the effective oxidation of alkenes [23][24][25][26][27][28]. The aforementioned results showed that new protocols and mechanisms of these transformations have been developed in past decades.…”
