Supported platinum catalysts are studied for the reductiveamination of ketones under ammonia and hydrogen. For a model reaction with 2‐adamantanone, Pt‐loaded MoOx/TiO2 (Pt‐MoOx/TiO2) shows the highest yield of primaryamine. The catalyst is effective for the selective transformation of various aliphatic and aromatic ketones to the corresponding primaryamines, which demonstrates the first example
对负载的铂催化剂进行了研究,以在氨和氢下将酮还原胺化。对于与2-金刚烷酮的模型反应,负载Pt的MoO x / TiO 2(Pt-MoO x / TiO 2)显示出最高的伯胺收率。该催化剂对于将各种脂族和芳族酮选择性转化为相应的伯胺是有效的,这证明了通过该反应选择性合成伯胺的第一个实例。在催化剂上吸附的丙酮的红外光谱中,胺的产率随CO伸缩带负移的增加而增加,这表明载体材料上的路易斯酸位在该催化体系中起着重要的作用。
