Abstract

For generating cationic zirconocene species that are useful for organic synthesis, AgAsF6 proved to be an efficient catalyst that serves as a safe alternative to AgClO4. Scope and limitation is discussed on this new catalyst in the processes including (1) alkyl/alkenyl transfer reaction from organozirconocene chloride to aldehyde,(2) two-and four-carbon homologation of aldehyde,(3) dual synthetic methods of 1, 3-dienes from aldehydes/ ...
