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.
乙炔端基磺酰化物和其寡聚物是通过将磺酰基二苯酚与选择自间二溴苯、对二溴苯和它们的混合物的材料在钾碱的存在下反应来制备的,以形成双溴苯氧基二苯酚磺酰,然后将其与含有至少三个碳原子和紧邻乙炔基的碳原子上的羟基的取代末端乙炔化合物反应,以形成羟基乙炔端基苯氧基二苯酚磺酰,然后经过碱催化裂解以形成所需的乙炔端基磺酰化物和寡聚物。通过将磺酰基二苯酚与选择自间二溴苯、对二溴苯和它们的混合物的材料在钠基的存在下反应来制备羟基芳基乙炔基磺酰化物。得到的羟基苯基溴苯氧基苯磺酰可以:(1)与含有二硝基氟苯基的化合物反应,以形成二硝基乙炔基磺酰化物,然后与亚硫酸钠和氢氧化钠反应,以形成二氨基乙炔基磺酰化物;(2)与二溴苯反应,以形成双溴苯氧基二苯酚磺酰;或(3)与双溴苯氧基二苯酚磺酰反应,以形成寡聚溴苯氧基二苯酚磺酰,该寡聚物可用于形成寡聚乙炔端基磺酰化物。在制备乙炔端基磺酰化物时使用的金属杂质,如钯和铜,可通过将受金属污染的磺酰化物与氢卤酸混合,并将混合物与氨基化合物接触以形成金属污染物配合物而去除。
