Saturated aliphatic ester

WebbThis group is related to the group ‘Esters from linear saturated dicarboxylic acids and of linear or cyclic aliphatic alcohols’. Some of the substances from both groups belong to the same registrant’s category(ies) such as the ‘Polyfunctional liphatic Ester (PFAE) linear’ category and the ‘Dibasic ester’ category. Additionally, the WebbA. R. Jagdale, A. S. Paraskar, A. Sudalai, Synthesis, 2009, 660-664. A well-defined manganese (I) complex with a commercially available bisphosphine ligand catalyzes selective and efficient hydrosilylations of a broad range of esters to alcohols at 100 °C under solvent-free conditions.
