Efforts have resulted in the production of some trimethylsilyl-blocked diamines, which have been employed in a novel manner for the synthesis of polyimide model compounds. Three new silicon-containing diamides were prepared by reacting 1 mol of bis-/N, N prime-bis (trimethylsilyl) -4-aminophonyl/-disubstituted silanes with 2 mol of phthalic anhydride, thus establishing the reactivity of fully silylated diamides in imide formation.
Description of four new silicon-containing dianhydrides synthetized in an attempt to provide useful silicon-containing polyimide precursors. They were prepared by aqueous potassium permanganate-pyridine oxidations of corresponding tetramethyl intermediates to form tetracarboxylic acids, which were dehydrated to the dianhydrides.
