  Provided is a material that, when compared with SAPd, exhibits the similar activity in cross-coupling (CC) reactions, can decrease the amount of catalytic metal that is mixed into the reaction product, and increases the number of times use can be repeated. Provided are a catalyst and a catalyst precursor that use a catalytic metal other than Pd and that exhibit the CC reaction activity similar to when Pd is used. Provided are a catalyst and a catalyst precursor that exhibit the similar CC reaction activity when using Pd or a catalytic metal other than Pd, without using a carrier such as metal and without using piranha solution. A composite wherein catalytic metal nanoparticles are dispersed in a continuous phase comprising a polymer having C2-6 alkylene group units and phenylene group units (an alkylene group unit being bonded to at least the first and fourth position of the phenylene group unit). The particle diameter of the catalytic metal nanoparticles is at most 20 nm. A composite structure including a substrate, and the aforementioned composite provided to the surface of the substrate. A method for manufacturing the composite structure by dehydrocondensating, in the presence of a catalytic metal compound, a benzene compound having at least two alkyl groups (two of the alkyl groups being at the first and fourth position) in order to form the composite on the substrate surface.

  提供了一种材料，与SAPd相比，在交叉偶联（CC）反应中表现出类似的活性，可以减少混入反应产物中的催化金属量，并增加可重复使用的次数。提供了一种催化剂和催化剂前体，其使用除Pd之外的催化金属，并且展现出与使用Pd时相似的CC反应活性。提供了一种催化剂和催化剂前体，当使用Pd或除Pd之外的催化金属时，不使用金属载体或过氧化氢溶液，也表现出类似的CC反应活性。一种复合材料，其中催化金属纳米颗粒分散在包含C2-6烷基基团和苯基单元的聚合物连续相中（烷基基团与苯基单元的第一和第四位置至少结合）。催化金属纳米颗粒的粒径最大为20纳米。包括基底的复合结构，以及提供到基底表面的上述复合材料。通过在存在催化金属化合物的情况下，对至少具有两个烷基基团（其中两个烷基基团在第一和第四位置）的苯化合物进行脱氢缩合，以在基底表面形成复合材料的制造方法。
