Yield:-
Reaction Conditions:
with 2,2′,6,6′-tetrakis(dipyrrolyl phosphoramidite)-1,1′-diphenyl;chloro(1,5-cyclooctadiene)rhodium(I) dimer;hydrogen in toluene at 90; under 22502.3 Torr; for 5 h;Autoclave;Temperature;Reagent/catalyst;Solvent;Pressure;
Steps:
11-20; 2; 4; 6; 8; 10; 12 Example
General procedure: The application process of the catalyst for olefin hydroformylation reaction is as follows:In a 100mL autoclave, add 2mg of rhodium complex (0.00773mmoL) successively, the substrate is vinyl acetate (A) or ethyl vinyl ether (B), solvent toluene 10mL, phosphine ligand (0.0309mmol), and then charge Replace with syngas for three times, and refill with syngas to 3MPa; quickly raise the temperature to 80 and start stirring, timing; the reaction is finished after 5h, the autoclave is cooled to room temperature, and the reaction liquid is taken out; hydroformylation product Quantitative analysis was performed with Agilent GC-6890N gas chromatograph, capillary column using SE-30, hydrogen flame detector.
