Rhodium-Catalyzed Hydroformylation of Allyl Alcohol. A Potential Route to1,4-Butanediol

Iron Catalyzed Hydroformylation of Alkenes under Mild Conditions: Evidence of an Fe(II) Catalyzed Process

“…This anomalous behavior could be due to the weak σ-donation and lower coordinating ability of L2. At a higher ligand to metal ratio, the phosphite ligands are known to be slower, leading to longer reaction times, and the behavior noted here is in line with the previous reports . Incubating L2 for 24 h and in situ addition of substrate revealed slight improvement in the activity (Table , run 22).…”

Hydrocarbonylation reactions using alkylphosphine-containing dendrimers based on a polyhedral oligosilsesquioxane core

“…The mixtures were then dissolved in a suitable solvent (THF, MeCN or CH 2 Cl 2 ) before being transferred to the sample holder and dried. All mass measurements refer to peaks for the most common isotopes ( 1 H, 12 C, 16 O, 29 Si, 31 P).…”

“…These results show that, for butane-1,4-diol, the reaction proceeds, at least in part, through a sequential pathway (via aldehyde), but for the branched pathway leading to 2-methylpropan-1-ol, this is less certain. The failure to observe more than traces of the expected branched hydroxyaldehyde, 2methyl-3-hydroxypropan-1-al (selectivity of 1.4%), 29 and of its hydrogenated product, 2-methylpropane-1,3-diol (selectivity of 2.7%), after 15 min suggests that neither of these is an initial product nor can they be intermediates in the formation of 2-methylpropan-1-ol (see Table 6). Similar conclusions were drawn when using PEt 3 as the ligand.…”

Synthesis with Carbon Monoxide and a Petroleum Product

“…OH 2C 2 H 2 + CO + H 2 O -^* fOl + CO 2 (107) Finally, carbonylation of benzophenone and even benzene has been claimed 148 to produce anthraquinone in 90% yield by the use of a combination of Pd 11 chloride and Cu 11 chloride as catalyst (equation 108). The reaction (equation 107) also produces carbon dioxide.…”
