A novel photocatalytic urea synthesis strategy is proposed for the preparation of ureas from amines and carbon disulfide (CS), with Rhodamine B utilized as the photocatalyst. Conducted under mild reaction conditions, this method does not require the use of extra oxidants and efficiently yields a series of (un)symmetrical ureas and benzimidazolones under blue light irradiation. Furthermore, control
提出了一种新的光催化尿素合成策略,以罗丹明 B 作为光催化剂,由胺和二硫化碳 (CS) 制备尿素。该方法在温和的反应条件下进行,不需要使用额外的氧化剂,并且在蓝光照射下有效地产生一系列(不)对称的脲和苯并咪唑酮。此外,还进行了氧18标记对照实验,结果表明尿素产品中的羰基氧主要来自空气中的氧,通过氧化脱硫过程获得。
