WebThe energy level of orbital 22 (σ*) of CH 3 COCl in TS Cl reduced by 0.89 eV from free CH 3 COCl, which is larger than that in TS pyridine (0.25 eV). Therefore, more π* C O MO mix into orbital 22 in TS Cl compared to TS pyridine (as shown in Fig. 3 and 4). As a result, π* C O MO remains comparable contributions to σ* C–Cl in the ... WebThis study investigates the mechanism of metal-free pyridine phosphination with P(OEt)3, PPh3, and PAr2CF3 using density functional theory calculations. The results show that the reaction mechanism and rate-determining step vary depending on the phosphine and additive used. For example, phosphination of pyridine with P(OEt)3 occurs in five stages, …
