Ortho-Trialkylstannyl Arylphosphanes by C-P and C-Sn Bond Formation in Arynes

A novel and efficient approach to ortho-trialkylstannyl arylphosphanes by the reaction of arynes generated in situ with stannylated phosphanes (R3Sn-PR2) is described. Concurrent C-P and C-Sn bond formation occurs with high yields, and stannylated products are easily transformed into valuable ortho-substituted arylphosphanes. The reaction features high efficiency, good regioselectivity, and excellent practicality.

On the reaction of KPPh2 with Fe(CO)5 and Fe(CO)4CS; molecular structure of [(CO)4FePPh2]-

Fe(CO)5 reacts with [PPh2]- in THF at -78 °C to give the adduct [(CO)4FeCOPPh2]- (3) which decomposes at elevated temperature to give [(CO)4FePPh2]- (1), [Fe2(CO)8]2- (2) and (Ph2P)2 probably via a radical mechanism. Attempts to transfer 3 with the electrophiles MeSO3CF3 or Me3SnCl into the corresponding carbenes have failed and Fe(CO)5 along with Ph2PMe and Me3SnPPh2, respectively, are formed. 1 adds one equivalent of CS2 to generate [(CO)4FePPh2CS2]- (4). The [K-18-Krone-6] salt of 1 crystallizes in the triclinic space group P 1 with the unit cell parameters a = 929.5(2), b =1112.1 (2), c - 2017.9(4) pm, α = 100.29(3)°; β = 94.07(3)°; γ = 114.58(3)°. The existence of 3 is established by low temperature 31P NMR spectroscopy.

Stannylated phosphines. I. Preparation of (β-trimethylstannyl)alkyldiphenylphosphines

(β-Trimethylstannyl)alkyldiphenylphosphines can be readily prepared by addition of diphenylphosphine to the corresponding vinyltrimethyltin Me3SnCR=CH2 under free radical conditions.In contrast, free radical hydrostannation of the corresponding phosphines Ph2PCR=CH2 is a more complex process, and is apparently of little synthetic value.The title compound can be easily oxidised by potassium permanganate to give the corresponding phosphine oxides in good yields.Hydrostannation of model alkynyldiphenylphosphines (RCCPPh2, R=H, Me3Sn) occurs regiospecifically.
