TLDR
In this article, a series of phosphorus(III) compounds was found to have an intramolecular donor-acceptor interaction between NMe2 substituents and phosphorus.Abstract:
The reaction of MeOCH2CH2N(Me)SiMe3, Me2NCH2CH2OSiMe3, and Me2NCH2CH2N(Me)SiMe3 with PCl3. PhPCl2, and Ph2PCl was found to proceed with cleavage of the N[sbnd]Si or O[sbnd]Si bond and formation of the phosphorus(III) compounds, 3 to 8. In this series of, in part, novel phosphorus(III) compounds an intramolecular donor-acceptor interaction between NMe2 substituents and phosphorus has been observed which in the case of the product of the reaction of Me2NCH2CH2N(Me)SiMe3 with PCl3, led to a stable intramolecular complex, , 3a. The reversible formation of an intramolecular complex, as a function of temperature, has been observed for Me2NCH2CH2N(Me)P(Ph)Cl,4 while no evidence for an intramolecular interaction was noted for compounds 5, 6 and 8. For compound 7 which is obtained as a solid an intramolecular interaction between phosphorus and nitrogen seems likely in the solid state but cannot be observed by n.m.r. spectroscopy in solution in CDCl3. A single crystal X-ray structure determination for 3a h...read more

Ligand exchange and reaction mechanisms offluorinated compounds
TL;DR: A review of ligand exchange and reaction mechanisms of fluorinated compounds is presented in this article, with emphasis on the main group fluorides, where the main ligand exchanges are divided into a series of elementary steps of bond formation and bond dissociation, using the coordination model of reaction mechanisms as an organizing principle.

Solvent-modulated reactivity of PCl3 with amines
TL;DR: In this paper, the reactivity of phosphorus trichloride towards amines in ionic liquids has been investigated and compared with that in conventional organic solvents, and it has been shown that bis{(trifluoromethyl)sulfonyl}imide-based ionic liquid offers a tight control over the selectivity during the reaction and offer access to monoamination and bisamination products in high yields and chemoselectively.
