Lithium-Aluminate-Catalyzed Hydrophosphination Applications

Synthesized, isolated, and characterized by X-ray crystallography and NMR spectroscopic studies, lithium phosphidoaluminate iBu3AlPPh2Li(THF)3 has been tested as a catalyst for hydrophosphination of alkynes, alkenes, and carbodiimides. Based on the collective evidence of stoichiometric reactions, NMR monitoring studies, kinetic analysis, and DFT calculations, a mechanism involving deprotonation, alkyne insertion, and protonolysis is proposed for the [iBu3AlHLi]2 aluminate catalyzed hydrophosphination of alkynes with diphenylphosphine. This study enhances further the development of transition-metal-free, atom-economical homogeneous catalysis using common sustainable main-group metals.

Photocatalytic Hydrophosphination of Alkenes and Alkynes Using Diphenylphosphine and Triamidoamine-Supported Zirconium

Reactions of alkene or alkyne with diphenylphosphine and catalytic [κ5-N,N,N,N,C-(Me3SiNCH2CH2)2NCH2CH2NSiMe2CH2]Zr (1) are greatly enhanced under photolysis, providing viable catalytic hydrophosphination with a broad substrate scope. Whereas diphenylphosphine had been an inaccessible substrate under thermal conditions, complete conversion of alkene substrates to tertiary phosphine is achieved in as little as four hours at ambient temperature with 1 under ultraviolet irradiation. Previously inactive alkenes are now hydrophosphination substrates with diphenylphosphine to produce tertiary phosphine ligands possessing tunable steric and electronic properties.
