Heteropoly acid supported on silica gel (H3PW12O40/SiO2) is easily used as a heterogonous, reusable and efficient catalyst for the synthesis of N-substituted, 2- and 3-unsubstituted pyrroles in solution or under solvent-free microwaveirradiation. The catalyst can be easily recovered and reused for several times without loss of activity.
负载在硅胶上的杂多酸(H 3 PW 12 O 40 / SiO 2)易于用作在溶液中或在无溶剂条件下合成N-取代的2-和3-未取代的吡咯的,可重复使用的高效催化剂微波照射。该催化剂可以容易地回收并重复使用几次而不会损失活性。

This invention relates to the use of nano-organocatalysts, and, more specifically, to the use of magnetic nanomaterial-supported organocatalysts. It is an object of the present invention to provide “green” catalysts and protocols. According to one embodiment of the invention, a nano-organocatalyst in the form of a magnetic nanomaterial-supported organocatalyst is provided. According to other embodiments of the invention, glutathione and cysteine are provided as organocatalysts and magnetic nanomaterial-supported glutathione and magnetic nanomaterial-supported cysteine are provided for use as nano-organocatalysts. According to another embodiment of the invention, a method of using a recyclable magnetic nanomaterial-supported organocatalyst using a totally benign aqueous protocol, without using any organic solvent in the reaction or during the workup, is provided. According to a further embodiment of the invention, a recyclable magnetic nanomaterial-supported organocatalyst for various organocatalytic reactions, including but not limited to Paal-Knorr reactions, aza-Michael addition and pyrazole synthesis, is provided.
