The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Diphenyl-2-pyridylphosphine, is researched, Molecular C17H14NP, CAS is 37943-90-1, about Palladium-Catalyzed Cascade Carbonylation to α,β-Unsaturated Piperidones via Selective Cleavage of Carbon-Carbon Triple Bonds, the main research direction is alpha beta unsaturated piperidone preparation; propargylic alc aliphatic amine cascade carbonylation palladium catalyst; bond cleavage; cascade carbonylation; homogeneous catalysis; palladium; α,β-unsaturated piperidones.Synthetic Route of C17H14NP.
A direct and selective synthesis of α,β-unsaturated piperidones by a new palladium-catalyzed cascade carbonylation is described. In the presented protocol, easily available propargylic alcs. react with aliphatic amines to provide a broad variety of interesting heterocycles. Key to the success of this transformation is a remarkable catalytic cleavage of the present carbon-carbon triple bond by using a specific catalyst with 2-diphenylphosphinopyridine as ligand and appropriate reaction conditions. Mechanistic studies and control experiments revealed branched unsaturated acid as crucial intermediate.
