Symmetrical and unsymmetrical 1,3-diphosphoryl substituted (E)-propenes were synthesized by the reaction of 1-acetoxyallyl substituted phosphorus compounds (phosphonates, phosphinates, and phosphine oxides) with O,O-dialkyl phosphonates (O-alkyl phosphinates, or dialkyl phosphine oxides) and bis(trimethylsilyl)acetamide (BSA) in the presence of nickel(II) chloride as catalyst, or with trivalent phosphorus acid esters (phosphites, phosphonites, and phosphinites) using only nickel(II) chloride as the catalyst.
合称对称和非对称的1,3-二磷酸基取代(E)-烯丙烯,是通过1-乙酰氧基烯丙基取代的磷化合物(磷酸酯、磷酸亚酯和磷烯氧化物)与O,O-二烷基磷酸酯(O-烷基磷酸亚酯或二烷基磷烯氧化物)以及双(三甲基硅基)乙酰胺(BSA)在氯化镍(II)作为催化剂的存在下反应合成的,或者与三价磷酸酯(磷酸酯、磷酸亚酯和磷酸亚磷酯)仅使用氯化镍(II)作为催化剂反应。
