2-Phenylseleno aldehydes and ketones were selectively obtained using solid-supported catalyst (KF/Al2O3) and PEG-400 as clean, recyclable medium in good to excellent yields. The method was applied in the preparation of highly functionalized 2-phenylseleno citronellal and citronellol, potential bactericide agents. The catalytic system KF/Al2O3 and PEG-400 can be re-used for four times without previous
使用固体负载的催化剂(KF / Al 2 O 3)和PEG-400作为清洁的可回收介质,以良好或优异的收率选择性地获得了2-苯基硒醛醛和酮。该方法用于制备高度功能化的2-苯基硒代香茅醛和香茅醇(潜在的杀菌剂)。催化系统KF / Al 2 O 3和PEG-400可以重复使用四次,而无需事先处理。
