Chemistry and Application of Phosphonium and Arsonium Ylides (XV——A Facile Synthesis of Dimethyl 3,7-Diperfluoroalkyl-2,4,7-Nonatriendioates

摘要

We reported the stereoselectlve synthesis of fluorine-containing trisubstituted ethylenes(4) by hydrolysis of the adducts(3) which are the products of the reactions of some stable phosphonium or arsonium ylides with methyl 2-perfluoroalkynoates(2).
