Lee, Dae-Yon; Kim, In-Jung; Jun, Chul-Ho published the artcile< Synthesis of cycloalkanones from dienes and allylamines through C-H and C-C bond activation catalyzed by a rhodium(I) complex>, SDS of cas: 112-63-0, the main research area is cycloalkanone preparation alkadiene allylamine rhodium catalyzed carbon hydrogen activation; phenylpropenyl pyridinamine alkadiene rhodium catalyzed activation cycloalkanone preparation.
An allylic amine, 3-methyl-N-(3-phenyl-2-propenyl)-2-pyridinamine (I), is used as a masked form of formaldehyde in the rhodium-catalyzed cyclization of dienes. The reaction provides access to various cycloalkanones through chelation-assisted C-H-bond and C-C-bond activation. The di-μ-chlorotetrakis[(1,2-η)-cyclooctene]dirhodium/tricyclohexylphosphine-catalyzed reaction of I with [[(1-ethenyl-3-butenyl)oxy]methyl]benzene gave 4-(phenylmethoxy)cycloheptanone (II) and 2-methyl-4-(phenylmethoxy)cyclohexanone (III) (84% overall yield; 67:33 ratio). Also, allylic amines that have no coordination site could be applied to this reaction; for example, N-(3-Phenyl-2-propenyl)benzenamine reacted with [[(1-ethenyl-3-butenyl)oxy]methyl]benzene in the presence of 3-methyl-2-pyridinamine catalyzed by di-μ-chlorotetrakis[(1,2-η)-cyclooctene]dirhodium/tricyclohexylphosphine gave II and III (72% overall yield; 53:47 ratio).
Angewandte Chemie, International Edition published new progress about Acylation. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, SDS of cas: 112-63-0.
