Abstract

An efficient bis(2-dodecylsulfanyl-ethyl)-amine·CrCl complex supported on KCC-1 (KCC-1/SNS/Cr) has been developed for the synthesis of spiroindenopyridazine-4-pyran, providing excellent yields of the corresponding products with remarkable chemoselectivity. This morphology ultimately leads to higher catalytic activity for the KCC-1-supported nanoparticles. The KCC-1/SNS/Cr NPs were thoroughly characterized by using TEM, SEM, TGA, FT-IR, ICP-MS, and BET. The recycled catalyst has been analyzed by ICP-MS showing only minor changes in morphology after the reaction, thus confirming the robustness of the catalyst.

摘要

一种负载在KCC-1上的高效双（2-十二烷基硫烷基-乙基）-胺·CrCl配合物（KCC-1/SNS/Cr）已被开发用于合成螺茚并哒嗪-4-吡喃，能以优异的产率得到相应产物且具有显著的化学选择性。这种形态最终导致负载在KCC-1上的纳米颗粒具有更高的催化活性。通过透射电子显微镜（TEM）、扫描电子显微镜（SEM）、热重分析（TGA）、傅里叶变换红外光谱（FT-IR）、电感耦合等离子体质谱（ICP-MS）和比表面积测定（BET）对KCC-1/SNS/Cr纳米颗粒进行了全面表征。通过ICP-MS对回收的催化剂进行分析，结果表明反应后其形态仅有微小变化，从而证实了该催化剂的稳定性。
