Abstract

The cellulosic hollow tube fiber fabricated from Calotropis procera supported BF₃ Lewis acid (BF₃@CPF) was prepared and investigated as nano- reactor and efficient catalyst for the N-formylation of amines. The morphology and physicochemical properties of the composite were characterized by FT-IR, X-ray diffraction, EDX, FE-SEM, and TGA analysis. The composite demonstrated high performance in N-formylation reaction with short time, high yield, and high selectivity. The catalyst showed high reusability, and the catalytic activity was retained constant over six consecutive cycles. The selectivity of the reaction was investigated. The results showed selectivity for secondary amines is higher than for primary amines. Additionally, aromatic amines have lower selectivity than aliphatic amines. FT-IR, ¹³CNMR, and ¹HNMR were used to confirm the chemical structure of the products.

纤维负载的BF3复合材料中空管：n -甲酰化的高效催化剂和纳米反应器

以卡罗贝斯（Calotropis procera）负载BF3 Lewis酸（BF3@CPF）为原料制备纤维素空心管纤维，并对其作为n -甲酰化胺的纳米反应器和高效催化剂进行了研究。采用FT-IR、x射线衍射、EDX、FE-SEM和TGA等分析手段对复合材料的形貌和理化性质进行了表征。该复合材料在n -甲酰化反应中表现出时间短、收率高、选择性高等特点。该催化剂具有较高的可重复使用性，在连续6次循环中催化活性保持不变。考察了反应的选择性。结果表明，仲胺的选择性高于伯胺。此外，芳香胺的选择性比脂肪胺低。利用FT-IR、13CNMR和1HNMR对产物的化学结构进行了确证。

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
