dc.description.abstract	The focus of the research involves a convenient method for a synthesis of bis(2,2,2-trifluoroethyl)phosphonoalkynes 43-a-d. The reaction was smooth and achieved good yields (50-60%). The bis(2,2,2-trifluoroethyl)phosphonoalkynes are good dienophiles in cylcoaddition reactions. After successful synthesis of bis(2,2,2-trifluoroethyl)phosphonoalkynes 43a-d, we synthesized vinyl phosphonates 46a-d, aryl phosphonates 48a-d in moderate yields by using Diels-Alder reaction. Cyclopentadiene and 1,3-cyclohexadiene were used as dienes. The products and by-products were purified by vacuum distillation and flash column and characterized by chromatographic (GC) and spectroscopic (NMR, MS) techniques.	en_US
