Abstract
Terephthalic acid hydrazide (1) was reacted with phenylphosphonic dichloride to yield bis(1,3,4,2-oxadiazaphosphole) derivative 3, which was condensed with α-aminophosphonic acid derivative 4 to afford bis[(1,2,4,3-triazaphospholyl)(chromonyl)methylphosphonic acid] derivative 5. The addition of diethyl phosphite to Schiff bases 9 and 10 derived from the condensation of bis(4-amino-1,2,4,3-triazaphosphole) derivative 6 or bis(4-phosphorylamino-1,2,4,3-triazaphosphole) derivative 7 with 3-formyl-6-methylchromone (8) yielded bis[(1,2,4,3-triazaphospholyl)(chromonyl)aminomethylphosphonate] derivative 11 and bis[(1,2,4,3-triazaphospholyl)(chromonyl)phosphorylamino-methylphosphonate] derivative 12, respectively. The structures of all products were established by elemental analysis and spectral data. © 2009 Wiley Periodicals, Inc.
