Abstract
The present invention relates to: a method for converting a hydroxyl group of an alcohol; and a catalyst which makes the method possible. A method for converting a hydroxyl group of an alcohol according to the present invention is characterized by producing a compound represented by CH(R)(R)Nu (wherein R, Rand Nu are as defined below) by reacting an alcohol represented by CH(R)(R)OH (wherein each of Rand Rrepresents a hydrogen atom, an optionally substituted alkyl group, or the like) and a compound having an active proton, which is represented by H-Nu (wherein Nu represents a group represented by —CHX-EWGor —NRR; Xrepresents a hydrogen atom or the like; EWGrepresents an electron-withdrawing group; and each of Rand Rrepresents a hydrogen atom, an optionally substituted alkyl group, or the like), with each other in the presence of a complex of a group 7-11 metal of the periodic table and at least one solid base that is selected from the group consisting of layered double hydroxides, composite oxides and calcium hydroxide.
