Herein, we report the first example of efficient reductive amination of ketones/aldehydes with amines using BH3N(C2H5)3 as a catalyst and a reductant under mild conditions, affording various tertiary and secondary amines in excellent yields. A mechanistic study indicates that BH3N(C2H5)3 plays a dual function role of promoting imine and iminium formation and serving as a reductant in reductive amination. This journal is

Paragraph 0114; 0119, (2019/05/18)
PROBLEM TO BE SOLVED: To provide a squarylium compound which is excellent in solubility in an organic solvent and is capable of selectively absorbing light in a red to near-infrared region while transmitting light in a visible light region at a high transmittance when forming a resin cured product. SOLUTION: The squarylium compound is represented by formula (1) (R1 and R6 are each independently a substituted/unsubstituted C3 or higher branched alkyl group; R2 and R7 are each independently a substituted/unsubstituted C5 or higher linear alkyl group; R3, R4, R8 and R9 are each independently H, an organic group or a polar functional group; and ring A and ring B are each independently a substituted/unsubstituted five- or more-membered nitrogen-containing heterocyclic ring).

A Pd/C/Zn mixture with alcohols has been revealed to be an efficient transfer hydrogenation system to quinolines. Furthermore, the metals mixture is able to activate alcohols as N-alkylating agents in a hydrogen autotransfer process. 1,2,3,4-Tetrahydroquinolines and N-alkylated tetrahydroquinolines from quinolines have been obtained with excellent yields in one step.
