摘要：

The synthesis of trans-1,4-bis(diphenylphosphino)-1,3-butadiene (1) was accomplished via the reaction of lithium diphenylphosphide with 1,1,2,3,4,4-hexachlorobutane. Crystals suitable for X-ray diffraction were acquired by slow evaporation of solvent. Compound 1 crystallized in the monoclinic space group P2(1)/n (14), a = 9.068(2) Angstrom, b = 25.862(5) Angstrom, c = 10.068(5) Angstrom, beta = 107.69(3)degrees, V = 2249(2) Angstrom(3), Z = 4. Compound 1 shows the diphenylphosphino units attached to the 1 and 4 carbons of a 1,3-butadiene spacer separated by 7.2 Angstrom. Compound 1 reacts with two equivalents of the W(CO)(5)(THF) to yield ditungstendecacarbonyl-[mu-1,4-bis(diphenylphosphino)-1,3-butadiene] (2).
