    • Acetylene terminated sulfones and oligomers thereof are prepared by reacting a sulfonyldiphenol with a material selected from the group consisting of a meta-dibromobenzene, a para-dibromobenzene and mixtures thereof in the presence of a potassium base to form a bis-bromophenoxydiphenyl sulfone, which is reacted with a substituted terminal acetylene compound containing at least three carbon atoms and an hydroxy group on the carbon atom adjacent to the acetylene group to form an hydroxy-acetylene terminated phenoxydiphenyl sulfone, which is then subjected to base catalyzed cleavage to form the desired acetylene terminated sulfones and oligomers. An hydroxy-arylacetylene terminated sulfone is prepared by reacting a sulfonyldiphenyl with a material selected from the group consisting of meta-dibromobenzene para-dibromobenzene and mixtures thereof in the presence of a sodium base. The resulting hydroxyphenylbromophenoxyphenyl sulfone can be: (1) reacted with a substituted terminal acetylene compound to form an hydroxy-arylacetylene terminated sulfone which in turn can be reacted with a dinitrofluorobenzene to form a dinitro-acetylene terminated sulfone which in turn can be reacted with sodium dithionite and sodium hydroxide to form a diaminoacetylene terminated sulfone; (2) reacted with a dibromobenzene to form a bis-bromophenoxydiphenyl sulfone; or (3) reacted with a bis-bromophenoxydiphenyl sulfone to form an oligomeric bromophenoxydiphenyl sulfone, which can be used to form an oligomeric actylene terminated sulfone. Metal contaminants, such as palladium and copper, used in the preparation of the acetylene terminated sulfones are removed by admixing the metal contaminated sulfone with a hydrogen halide and then contacting the admixture with an amino compound to complex the metal contaminant.
    • 乙炔封端的砜及其低聚物是通过在钾碱存在下使磺酰基二苯酚与选自间二溴苯,对二溴苯及其混合物的材料反应形成双溴苯氧基二苯砜来制备的, 与在乙炔相邻的碳原子上含有至少三个碳原子和羟基的取代的末端乙炔化合物反应形成羟基 - 乙炔封端的苯氧基二苯基砜,然后进行碱催化裂解以形成所需的乙炔终止 砜和低聚物。 羟基 - 芳基乙炔封端的砜通过在钠碱存在下使磺酰基二苯与选自间二溴苯对二溴苯及其混合物的材料反应来制备。 所得的羟基苯基溴苯氧基苯砜可以是:(1)与取代的末端乙炔化合物反应形成羟基 - 芳基乙炔封端的砜,其又可以与二硝基氟苯反应形成二硝基乙炔封端的砜,其又可以与钠反应 连二亚硫酸盐和氢氧化钠以形成二氨基乙炔封端的砜; (2)与二溴苯反应形成双溴苯氧基二苯砜; 或(3)与双溴苯氧基二苯砜反应形成低聚溴苯氧基二苯砜,其可用于形成低聚丙烯封端的砜。 通过将金属污染的砜与卤化氢混合,然后将该混合物与氨基化合物接触以使金属污染物复合,来除去用于制备乙炔封端的砜的金属污染物,例如钯和铜。

    • Bromoarylacetylenes such as m-bromophenylacetylene and certain precursors to such bromoarylacetylene are prepared by reacting an aryldibromide with a substituted terminal acetylene compound containing at least three carbon atoms and a hydroxy group on the carbon atom adjacent to the acetylene group in the presence of a dialkyl or trialkyl amine solvent and a catalyst system consisting of a palladium complex containing two halogen moieties and two tri-substituted phosphine moieties. Additional triphenylphosphine can be added. A cuprous iodide promoter is also employed in the reaction sequence. The bromoarylacetylenes can be reacted with a substituted terminal acetylene compound as defined using the same catalyst system as defined to produce the corresponding aryldihydroxy substituted acetylenes. Certain bromophenylhydroxy substituted acetylenes are claimed as new compositions.
    • 溴芳基乙炔如间溴苯乙炔和这种溴代芳基乙炔的某些前体通过在二烷基或二烷基乙炔的存在下使芳基二溴化物与在乙炔基附近的碳原子上含有至少三个碳原子和羟基的取代的末端乙炔化合物反应来制备, 三烷基胺溶剂和由含有两个卤素部分和两个三取代膦部分的钯络合物组成的催化剂体系。 可添加额外的三苯基膦。 在反应顺序中也使用碘化亚铜助催化剂。 溴代芳基乙炔可以与使用与所定义相同的催化剂体系所定义的取代的末端乙炔化合物反应,生成相应的芳基二羟基取代的乙炔。 作为新组合物要求某些溴苯基羟基取代的乙炔。
