摘要： The present invention provides a polysaccharide supported fluorinating agents which can be used in fluorination reactions. The invention particularly describes a new bacterial cellulose supported tetra-n-butyl ammonium fluoride complex [NBu4(Bac-Cell-OH)F] which is stable and non-hygroscopic. The invention further relates to a process for fluorination using the [NBu4(Bac-Cell-OH)F] complex.
