説明
Abstract The Ru 3 (CO) 12 /1,10-phenanthroline-catalyzed hydroformylation of styrene under 100 atm of syngas (CO:H 2 =1:1) at 120°C in DMF gives the corresponding branched and linear aldehydes in 58 and 22% yields, respectively. With the use of quinuclidine as a ligand in place of 1,10-phenanthroline in N , N -dimethylacetamide, the corresponding branched and linear oxo-alcohols were obtained in 53 and 28% yields, respectively. Hydroformylation of methyl acrylate by a catalyst system of Ru 3 (CO) 12 /1,10-phenanthroline to afford 4-methoxy-4-methyl- δ -valerolactone 1 in 31% yield, while the catalyst system of Ru 3 (CO) 12 /PPh 3 yields the open-chain aldehyde, dimethyl 2-formyl-2-methylglutarate ( 3 ), which is the precursor of lactone 1 in 18% yield.
