Spinello, Brian J.; Wu, Jessica; Cho, Yoon; Krische, Michael J. published the artcile< Conversion of Primary Alcohols and Butadiene to Branched Ketones via Merged Transfer Hydrogenative Carbonyl Addition-Redox Isomerization Catalyzed by Rhodium>, Formula: C13H19BrN4O2, the main research area is isobutyl ketone preparation; alc butadiene tandem carbonyl addition redox isomerization rhodium catalyst; aldehyde butadiene tandem reductive coupling redox isomerization rhodium catalyst.
The first examples of rhodium-catalyzed carbonyl addition via hydrogen autotransfer were described, as illustrated in tandem butadiene-mediated carbonyl addition-redox isomerizations that directly converted primary alcs. to iso-Bu ketones RC(O)CH(Me)Et [R = 3-MeOC6H4, 3,4,5-tri-MeOC6H2, benzothiophen-5-yl, etc.]. Related reductive coupling-redox isomerizations of aldehyde reactants mediated by sodium formate also were reported. A double-labeling crossover experiment revealed that the rhodium alkoxide obtained upon carbonyl addition enacted redox isomerization without dissociation of rhodium at any intervening stage.
Journal of the American Chemical Society published new progress about Addition reaction. 374930-88-8 belongs to class piperazines, and the molecular formula is C13H19BrN4O2, Formula: C13H19BrN4O2.
