Research on Organofluorine Chemistry for 700 Degrees F Thermooxidative Stability

Abstract

Much exciting chemistry has been completed over the three year course of this grant. The 32-membered fluorinated multifunctional heterocycle (C(O) N(CH3)SO2(CF2)2O(CF2)4O(CF2)2(SO2)(CH3)NC(O))2 was prepared and a crystal structure was obtained. New, efficient routes for the preparation of fluorinated amines and azaalkenes have been developed, and several members of a nearly unknown class of compounds, i.e., fluoroalkyl(aryl)tetraazanes were prepared and characterized. Methods were also developed for the synthesis of perfluoropropylidene containing aromatic and alkyl ethers. R, transfer reagents, e.g., CF3Si(CH3)3 and C6F5Si(CH3)3 as well as R(sub f)OSi(CH3)3 were prepared and applied to the preparation of novel ethers, and substituted aromatic compounds. Several fluorinated macroheterocycles were synthesized using multifunctional silanes and siloxanes. The chemistry of perfluorovinylamines has been explored in some detail.
