The reactions of pentafluoroaniline with aromatic CX3-derivatives (X = F, Cl) in the presence of AlCl3 were studied.It was shown that compounds with a CF3 group can be used in reactions with polyaromatic amines instead of CCl3 - derivatives for the synthe
Fluorinated bis(phenoxyketimine)titanium complexes for the living, isoselective polymerization of propylene: Multiblock isotactic polypropylene copolymers via sequential monomer addition

A series of bis(phenoxyketimine)titanium dichloride complexes were synthesized and evaluated as catalysts for living, isoselective propylene polymerization upon activation with methylaluminoxane (MAO). Catalysts bearing phenoxyketimine ligands with different substituents at the ortho and para positions of the phenolate ring and substituents at the ketimine carbon were investigated. The identity of the ketimine substituent had the largest effect on the activity and isoselectivity of propylene polymerization. Complex 12/MAO promoted the living, isoselective polymerization of propylene ([m4] = 0.73, α = 0.94). This catalyst system was used for the synthesis of a number of block copolymers featuring isotactic polypropylene semicrystalline blocks and poly(ethylene-co-propylene) amorphous blocks. Several triblock samples with varying block lengths, a pentablock, and a heptablock copolymer were synthesized. Mechanical testing has revealed that each is elastomeric with elongations at break between ～790-1000%.

Reactions of some polyfluorinated amines of the benzene, diphenyl, naphtalene and pyridine series with CCl4 in the presence of AlCl3 have been investigated.A new method is proposed for producing polyfluoroarylcarbonimidoyl dichlorides ArfN=CCl2.The reaction is shown to be sufficiently general and applicable in the series of polychlorinated anilines and low-base anilines of the hydrocarbon series as well.The possibility of involving other compounds of the type CCl3R and other Lewis acids in the reaction has been studied.The factors influencing the course of the reaction and the mechanism of formation of polyfluoroarylcarbonimidoyl dichlorides are discussed.
