A divergent visible-light-induced Ph3P-promoted method for the synthesis of ureas and formamides from amines and CO2 is reported. Without external additions, a range of ureas could be directly accessed under ambient temperature and pressure. Using triisopropylsilanethiol as the hydrogen source, formamides could be produced.

Zhao, Yichao; Bruce, Lachlan David; Jin, Jianwen; Xia, Bo; Chan, Philip Wai Hong published the artcile< Copper catalyzed N-formylation of α-silyl-substituted tertiary N-alkylamines by air>, HPLC of Formula: 6280-57-5, the main research area is dialkylaminomethyl trimethylsilane copper catalyst formylation; dialkyl formylamine preparation.

A site-selective method to prepare N-formyl amines efficiently that relies on the copper(I)-catalyzed oxidation of α-silyl-substituted tertiary N-alkylamines by air at room temperature was described. The oxidative protocol was shown to exhibited excellent functional group tolerance as it was applicable to a wide variety of amine substrates and a number of bioactive mols. and natural products. Moreover, it delinates a ligand- and additive-free amine oxidation process mediated by a low-cost metal salt with oxygen from air taking on the role of both the terminal oxidant and as part of the formylation reagent, which was unprecedented in copper catalysis. It also offered the first synthetic method that can selectively generate α-amino radical species as reactive intermediates from α-silylamines under non-photochem. reaction conditions.

Toigawa, Tomohiro; Peterman, Dean R.; Meeker, David S.; Grimes, Travis S.; Zalupski, Peter R.; Mezyk, Stephen P.; Cook, Andrew R.; Yamashita, Shinichi; Kumagai, Yuta; Matsumura, Tatsuro; Horne, Gregory P. published the artcile< Radiation-induced effects on the extraction properties of hexa-n-octylnitrilo-triacetamide (HONTA) complexes of americium and europium>, Category: amides-buliding-blocks, the main research area is radiation induced extraction hexa octylnitrilo triacetamide complex americium europium.

The candidate An(III)/Ln(III) separation ligand hexa-n-octylnitrilo-triacetamide (HONTA) was irradiated under envisioned SELECT (Solvent Extraction from Liquid waste using Extractants of CHON-type for Transmutation) process conditions (n-dodecane/0.1 M HNO3) using a solvent test loop in conjunction with cobalt-60 gamma irradiation The extent of HONTA radiolysis and complementary degradation product formation was quantified by HPLC-ESI-MS/MS. Further, the impact of HONTA radiolysis on process performance was evaluated by measuring the change in 243Am and 154Eu distribution ratios as a function of absorbed gamma dose. HONTA was found to decay exponentially with increasing dose, affording a dose coefficient of d = (4.48 ± 0.19) x 10-3 kGy-1. Multiple degradation products were detected by HPLC-ESI-MS/MS with dioctylamine being the dominant quantifiable species. Both 243Am and 154Eu distribution ratios exhibited an induction period of ~70 kGy for extraction (0.1 M HNO3) and back-extraction (4.0 M HNO3) conditions, after which both values decreased with absorbed dose. The decrease in distribution ratios was attributed to a combination of the destruction of HONTA and ingrowth of dioctylamine, which is capable of interfering in metal ion complexation. The loss of HONTA with absorbed gamma dose was predominantly attributed to its reaction with the n-dodecane radical cation (R ̇+). These R ̇+ reaction kinetics were measured for HONTA and its 241Am and 154Eu complexes using picosecond pulsed electron radiolysis techniques. All three second-order rate coefficients (k) were essentially diffusion limited in n-dodecane indicating a significant reaction pathway: k(HONTA + R ̇+) = (7.6 ± 0.8) x 109 M-1 s-1, k(Am(HONTA)2 + R ̇+) = (7.1 ± 0.7) x 1010 M-1 s-1, and k(Eu(HONTA)2 + R ̇+) = (9.5 ± 0.5) x 1010 M-1 s-1. HONTA-metal ion complexation afforded an order-of-magnitude increase in rate coefficient Nanosecond time-resolved measurements showed that both direct and indirect HONTA radiolysis yielded the short-lived (<100 ns) HONTA radical cation and a second long-lived (μs) species identified as the HONTA triplet excited state. The latter was confirmed by a series of oxygen quenching picosecond pulsed electron measurements, affording a quenching rate coefficient of k(3[HONTA]* + O2) = 2.2 x 108 M-1 s-1. Overall, both the HONTA radical cation and triplet excited state are important precursors to the suite of measured HONTA degradation products.
