Related Products of 5704-04-1, Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. The appropriate choice of redox mediator can avoid electrode passivation and overpotential. 5704-04-1, Name is 2-((1,3-dihydroxy-2-(hydroxymethyl)propan-2-yl)amino)acetic acid, SMILES is O=C(O)CNC(CO)(CO)CO, belongs to amides-buliding-blocks compound. In a article, author is Kaneko, Ryuji, introduce new discover of the category.
High functional group compatibility of iridium-catalyzed synthesis of enamines from amides and 1,1,3,3-tetramethyldisiloxane (TMDS) realized facile access of a series of donor (D)-pi-acceptor (A)-conjugated enamines, in which enamine behaves as a donor functional group. The amide precursors containing reducible functional groups, such as halogen, carbonyl, and nitro groups, underwent reaction with TMDS to give the corresponding enamines in high yields. In most cases, chemoselective hydrosilane reduction of the amide group occurred while other reducible groups remained intact. Absorption and emission properties including solvatochromic behavior for the resulting D-pi-A-conjugated enamines were determined using UV-visible and fluorescent spectra, which provided an understanding of the donor properties of the CH=CHNPh2 group and photofunctional properties of the D-pi-A conjugated enamines as a fluorescent dye. Maximum absorption wavelength (lambda(abs)) of p-ZC(6)H(4)CH=CHNPh2 was predictable from lambda(abs) of p-ZC(6)H(4)NPh(2), which was supported by density functional theory calculations. Some of the D-pi-A-conjugated enamines showed fluorescence with moderate fluorescence quantum yields (Phi(fl)). Of interest are unusually emissive pi-conjugated enamines containing a nitro group, which generally behaves as strong quenchers of fluorescence. The additive effect of B(C6F5)(3) resulted in significant red shifts of lambda(abs) and lambda(fl). In some cases, high Phi(fl) was observed in the solution state.
