Palladium(II) phthalocyanine (PdPc) tetrasulfonate was chemically bonded to an amine moiety of chitosan aerogel. The reaction was promoted by the transformation of sulfonic acid groups of PdPc to sulfonyl chloride, which is highly active for amination. The porous composite showed good catalytic activity in the oxidation reaction of some alkylarenes, aliphatic and benzylic alcohols, and cyclohexanol. High conversions and excellent selectivities were obtained for the solvent-free reactions under aerobic conditions at 80 °C during 24 h. While many oxidation reactions have been reported catalysed with palladium phthalocyanine, this is the first reported oxidation of alkylarenes via this catalyst. The organometallic compound is applicable as a heterogeneous catalyst having high chemical stability with recyclability up to six times.
钯（II）酞菁（PdPc）四磺酸盐通过化学键合到壳聚糖气凝胶的胺部分上。该反应是通过将 PdPc 的磺酸基团转化为磺酰氯来促进的，磺酰氯对于胺化反应具有很高的活性。多孔复合材料在一些芳基烷基、脂肪族和苄醇以及环己醇的氧化反应中表现出良好的催化活性。在无溶剂条件下，在 80°C 下有氧条件下反应 24 小时，即可获得高转化率和优异的选择性。虽然已经报道了许多使用钯酞菁催化的氧化反应，但这是该催化剂首次报道用于芳基烷基的氧化。该有机金属化合物可用作多相催化剂，具有高化学稳定性，可重复使用六次。
