Phosphonate derivatives of pyridine grafted onto oxide nanoparticles
摘要:
The synthesis of phosphonate derived stilbazole 1 by using a Heck reaction is described. The reactivity of the pyridine moiety is studied. After hydrolysis of the ethyl phosphonate groups, the grafting of phosphonic acid derived stilbazole 5 on metal oxides TiO2 or SnO2 is reported. The accessibility and reactivity of the pyridine moiety at the surface is demonstrated. (C) 2002 Published by Elsevier Science Ltd.
