RuCl22 has efficiently catalyzed the reduction of cyclohexanone and heptanal by sodium formate in chlorobenzene-water, using cetylpyridinium bromide as the phase transfer catalyst.In both cases, the reduction was first order both in t

Cu(acac)2 (1) is a highly active catalyst for the hydrophosphination of alkenes. Photocatalytic conditions are critical, and provide high conversions with unactivated substrates that have never before been reported with an air-stable catalyst or at ambient temperature. The commercial availability, ease of use, and broad substrate scope of compound 1 make hydrophosphination more available to synthetic chemists.

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.
