Ex(P−N)ding the chain. Salt elimination and lithiation strategies were employed in the step-wise synthesis of oligomers with P−N linkages having potential as environment friendly flame retardants due to their lack of anti-microbial activity.

C. The kinetic results of 1 are comparedwith those of Y-aryl phenyl chlorophosphates (2). The substrate 1 has one more identical substituent Ycompared to substrate 2. The cross-interaction between Y and Y, due to additional substituent Y, is significantenough to result in the change of the sign of cross-interaction constant (CIC) from negative ρ
C. 将1的动力学结果与Y-芳基苯基氯磷酸酯(2)的动力学结果进行了比较。与底物 2 相比,底物 1 具有多一个相同的取代基 Y。由于额外的取代基 Y,Y 和 Y 之间的交叉相互作用显着足以导致交叉相互作用常数 (CIC) 的符号从负 ρ 变化

We have developed a dual copper/photoredox-catalyzed approach for the construction of the P(O)–N bond from commercially available aromatic amines and P(O)–Hcompounds. This metallaphotoredox method avoids toxic or corrosive reagents and does not require prefunctionalized substrates. The reaction has a broad substrate scope and is suitable for the synthesis of phosphonamides and phosphinamides, thus

Versatile and concise Pd-catalyzed oxidative N-alkenylation of N-aryl phosphoramidates with alkenes is described in this study, a reaction that is of great significance but surprisingly unexploited. The transformation proceeds under mild reaction conditions, using O2 as a green oxidant and TBAB as an effective additive. An efficient catalytic system allows a variety of drug-related substrates to participate
