Provided are a water-soluble triarylphosphine for a palladium catalyst, which has high selectivity in a telomerization reaction and can be recovered with efficiency, an ammonium salt thereof, and a method for efficiently producing the same. Specifically, provided are bis(6-methyl-3-sulphophenyl)phenylphosphine; a bis(6-methyl-3-sulphonatophenyl)phenylphosphine diammonium salt obtained by reacting the phosphine with a tertiary amine having a total of 3 to 27 carbon atoms in groups bonded to one nitrogen atom; and a method for producing the same.
Photometric Characterization of the Reductive Amination Scope of the Imine Reductases from<i>Streptomyces tsukubaensis</i>and<i>Streptomyces ipomoeae</i>
reductive amination catalyzed by two promising imine reductases is established in a rapid photometric NADPH assay. Substrates ranging from aldehydes to ketones and from primary to secondaryamines are accepted, thus giving access to various secondary and tertiaryamine products.
