PREPARATION OF SILAZANE COMPOUND
-
Paragraph 0036; 0037, (2015/11/02)
A silazane compound useful as synthesis intermediates for paint additives, polymer modifiers, pharmaceuticals and agricultural chemicals is efficiently prepared by reaction of a halosilane compound with an amino-containing compound in a solvent which is the same silazane compound as the target product.

Melt copolymerization reactions of several bis(diethylamino)silane derivatives, bis(diethylamino)methylphenylsilane, bis(diethylamino) methyloctylsilane, 1,2-bis(diethylamino)tetramethyldisilane, and 1,3-bis(diethylamino)tetramethyldisiloxane, with 2,7-dihydroxyfluoren-9-one were carried out to yield poly[oxy(2,7-fluoren-9-onenylene)oxy(diorganosilylene)]s bearing the fluoren-9-one fluorescent aromatic group in the polymer main chain: poly[oxy(2,7-fluoren-9-onenylene)oxy(methylphenylsilylene)], poly[oxy(2,7-fluoren-9-onenylene)oxy(methyloctylsilylene)], poly[oxy(2,7- fluoren-9-onenylene)oxy(tetramethyldisilylene)], and poly[oxy-(2,7-fluoren-9- onenylene)oxy(tetramethyldisiloxanylene)]. These polymeric materials are soluble in common organic solvents such as CHCl3and THF. FTIR spectra of all the materials reveal characteristic Si-O-C stretching frequencies at 1012-1018 cm-1. In the THF solution, the prepared materials show strong maximum absorption peaks at 258-270 nm, strong maximum excitation peaks at 260-280 nm, and strong maximum fluorescence emission bands at 310-420 nm. TGA thermograms suggest that most of the polymers are essentially stable to 200 °C without any weight loss and up to 300 °C with only a weight loss of less than 5% in nitrogen.
