Thermal and oxidative stability of fluorinated alkyl aryl ethers

A series of compounds composed of hydrocarbon aryl components and fluorinated alkyl components joined by ether linkages were developed for evaluation as high performance lubricants. Thermal and oxidative stability of these compounds were evaluated. The basic molecular structure was shown to be highly durable against high temperature, even in air, which is an indispensable property if it is to be suitable as base stock for high performance lubricants. However, thermal and oxidative stability decreased when hydrogen atoms were present on carbons adjacent to benzene rings, especially in the case of the carbon at the center of the compound, which is adjacent to two benzene rings.

TMSCF3 as a Convenient Source of CF2=CF2 for Pentafluoroethylation, (Aryloxy)tetrafluoroethylation, and Tetrafluoroethylation

A new method for the on-site preparation of tetrafluoroethylene (TFE) and a procedure for its efficient use in pentafluoroethylation by fluoride addition were developed by using a simple two-chamber system. The on-site preparation of TFE was accomplished by dimerization of difluorocarbene derived from (trifluoromethyl)trimethylsilane (TMSCF3) under mild conditions. Other fluoroalkylation reactions, such as (aryloxy)tetrafluoroethylation and tetrafluoroethylation processes, were also achieved using a similar approach. This work not only demonstrates a convenient and safe approach for the generation and use of TFE in academic laboratories, but also provides a new strategy for pentafluoroethylation.
