Bidentate Ligands by Self-Assembly through Hydrogen Bonding: A General Room Temperature/Ambient Pressure Regioselective Hydroformylation of Terminal Alkenes
room temperature/ambient pressure regioselective hydroformylation of terminalalkenes with low catalyst loadings in good activity. The generality of this catalyst under these conditions was demonstrated for a wide range of structurally diverse alkenes equipped with many important functional groups. Thus, this practical and highly selective hydroformylation protocol, which omits the need for special pressure

low-cost hydroxyolefins allows accessing structurally complex amines of pharmaceutical relevance. Through the appropriate choice of auxiliary phosphorus ligands this tandem catalytic process can be directed to the formation of two different types of amines: aminoalcohols or aminotetrahydrofurans and aminotetrahydropyrans (starting from allylic and homoallylic alcohols, respectively).
regioselective hydroformylation of terminal alkenes, using cheap commercially available catalysts and ligands, in mild reaction conditions (70 °C, 9 bar, 40 min). The process can take advantages from both micellarcatalysis and microwave irradiation to obtain the linear aldehydes as the major or sole regioisomers in good to high yields. The substrate scope is largely explored as well as the application of hydroformylation
