英文摘要: The reaction of (E)-4-ethoxy-1,1,1-trifluoro-3-buten-2-one EtOCH=CHCOCF3 1 with diethyl phosphite (EtO)(2)P(O)H 2 afforded a 1: 1 cis- and trans-mixture of diethyl(1-trifluomethyl-3-etboxy)allyl-phosphate EtO-CH=CH-CH(CF3)OP(O)(OEt)(2) 3 via the 1,2-lambda(5) -oxaphosphol-4-ene intermediate. While tributyl phosphine Bu3P added to 1 giving the double addition product Bu3P+CH2-C-(COCF3)-CH=CH-COCF3 5. Its resonance structure was fully identified by spectral methods and single crystal X-ray diffraction analysis. More strong phosphorous nucleophile tris (diethyl amino) phosphine (Et2N)(3)P reacted with 1 to give the known compound (E)-4-(diethylamino)-1,1,1-trifluoro-3-buten-2-one Et2N-CH=CH-COCF3 10 in good yield.
