Abstract: A vinyl ether compound represented by formula (1-a) or formula (1-b): wherein n represents 0 or 1, and R1 and R2 each independently represent a hydrogen atom, a methyl group, or an ethyl group, provided that a total of the number of carbon atoms of R1 and the number of carbon atoms of R2 is 1 or 2.

Abstract: Esters and lactones can be respectively reduced to alcohols and diols in the presence of the Group 8 (VIII) transition metal complex, base and hydrogen gas (H2). An extremely practical reduction method can be provided by preferable combinations of the Group 8 (VIII) transition metal complex, the base, a used amount of the base, a pressure of hydrogen gas and a reaction temperature. This method is used in place of hydride reduction and is a useful method by which design of highly active catalysts can be relatively easily made while a high productivity can be expected.
