8:30 SYNTHESIS OF CHIRAL IMINES AND AMINES ON SILICA GEL, An-tonija Tangar *, Siddhi Shah and John T. Barbas, Valdosta State University, Valdosta, GA 31698. During the last few years we have been investigating the synthesis of imines on silica surfaces, molecular sieves, and anhydrous sodium sulfate. We then discovered a one pot synthesis of secondary amines on silica surfaces starting with primary amines and aldehydes or ketones. We would now like to report a facile, efficient, and greener method for the synthesis of chiral secondary amines starting with chiral primary amines and aldehydes. Typically, 2 g of activated silica, were introduced into a dry round bottomed flask equipped with a stirring bar and a drying tube. To this were added 20 mL of dry ether, 1.0x10-3 mol of an aldehyde and 1.0x10-3 mol of a chiral amine such as L(-)-[alpha]-Methylbenzylamine. The mixture was stirred for about 30 minutes to produce quantitatively the imine intermediate. To this mixture were then introduced 0.15 g of sodium borohydride and stirred briefly. The flask was then cooled in an ice bath and a few drops of water were added periodically to initiate reduction. This was followed by filtration and subsequent washing of the silica with three 5 mL aliquots of ether. The ether extracts were combined, dried over anhydrous sodium sulfate, and the ether removed under vacuum. The chiral amines were obtained in near quantitative yields. They were analyzed by IR, GC-MS, and proton and C-13 NMR. 8:45 NOVEL MACROMOLECULAR-INORGANIC HYBRID SYSTEMS WITH POTENTIAL MULTIFUNCTIONAL FIRE-RESISTANT ACTIVITITY, Joshua A. Valencia *, Sergey A. Isarov * and Gregory J. Gabriel, Kennesaw State University, Kennesaw, GA 30144. Char formation, oxygen dilution, and endothermic decomposition are the three most popular modes of action of effective flame retardants (FR). Our group has developed novel phosphonated polymers as potential FR additives. These polymers have excellent char forming properties and do not possess the biological and environmental toxicity inherent in halogenated FR. We will report the synthesis and thermal decomposition analysis of our polymers as well as results from controlled burn studies of polymer-treated paper strips. Recently, we have initiated a program to develop similar macromolecules that can modify the surface of Mg(OH)2, a popular, multifunctional FR filler which acts in all three ways described above. Thus we hope to construct further improved FR systems that safely slow or otherwise prevent flame formation and effectively reduce the need for typically-high Mg(OH)2 loading levels (20% - 60% by mass) in materials applications.
