Yield:-

Reaction Conditions:

with [Rh(CO){P(CH2CH2PPh2)3}]Cl;hydrogen in dichloromethane at 80; under 26252.6 Torr; for 5 h;Catalytic behavior;Overall yield = 71 %; regioselective reaction;Reagent/catalyst;

Steps:

Catalytic activity towards hydroformylation reaction
Catalytic activity towards hydroformylation reactionThe hydroformylation reactions were carried out in a Parr reac-tor. 2.5 mmol of the alkene and 0.005 mmol of the catalyst in 5 cm3DCM were placed in a 50 cm3reaction vessel. The reaction mixturewas purged with CO/H2(1:1) for about 5 min. The CO/H2pressurewas increased to 35 bar (actual pressure) at 25C in the closed reac-tor. The hydroformylation reactions were carried out at 80 ± 2C for3-8 h at 35 ± 2 bar. The reaction mixture was analyzed by GC andproducts were isolated by column chromatography taking hexaneand ethyl acetate as eluents.
