highly efficient synthesis of pyrano[2,3-c] pyrazole, amino-benzochromenes, amidoalkyl naphthol and 5-arylidene-2,4-thiazolidinedione derivatives. The application of Pine-SO3H in the synthesis offers several advantages such as simple procedure with an easy work-up, recoverable catalyst, mild condition, eco-friendliness, excellent yields, short reaction times and use of an inexpensive catalyst.
在此报告中,通过在180℃的密闭高压釜中以Pine-Cone作为碳基材料对硫酸进行热处理,合成了具有高酸密度的SO 3 H-官能化碳纳米颗粒(Pine-SO 3 H)。一步步骤。所得的纳米催化剂通过FT-IR,TGA,XRD,FE-SEM和元素分析(EA)进行表征。表征结果表明,碳基酸是无定形的,多环芳族碳片带有大量的-OH,-COOH和-SO 3 H基团。Pine-SO 3的催化活性在高效合成吡喃并[2,3-c]吡唑,氨基-苯并二甲酮,酰胺基烷基萘酚和5-亚芳基-2,4-噻唑烷二酮衍生物中研究了H。在合成中使用Pine-SO 3 H具有许多优点,例如操作简单,易于后处理,可回收的催化剂,条件温和,生态友好,产率高,反应时间短以及使用廉价的催化剂。
