Layered Double Hydroxides (LDHs): An Efficient Catalyst System for the Synthesis of Chiral Aminonitriles
Strecker reaction is one of the simplest multicomponent reactions. It used for synthesis of chiral α-amino nitriles. This reaction was carried out in the presence of catalytic amount of layered double hydroxides (LDHs). In this study, simple and practical method for the synthesis of this class of catalysts is provided. The results shown that LDH is the good heterogen catalyst for synthesis of c...
متن کاملLayered Double Hydroxides (LDHs): Versatile and Powerful Hosts for Different Applications
Layered double hydroxides (LDHs), also known as anionic clays or hydrotalcite-like materials, are a large family of 2D materials constituted by positively charged sheets of hydroxides intercalated by negatively charged anions. In general, the hydrotalcite structures are very robust, with a wide range of possible compositions and so with easily tunable functional properties. In fact, the most ap...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

متن کاملANION EXCHANGE REACTIONS OF LAYERED DOUBLE HYDROXIDES (LDHs) AND LAYERED HYDROXY SALTS (LHSs): QUANTIFICATION OF ION EXCHANGE Abstract Anion exchange reactions of a number of layered double hydroxides with inorganic anions
Anion exchange reactions of a number of layered double hydroxides with inorganic anions were investigated. The five LDH systems used in this study were Mg-Al, Ni-Al, Co-Al, Zn-Al and Zn-Cr. Ni-Zn hydroxynitrate and Ni-Zn hydroxyacetate were the LHSs used in this work. In general, all the LDHs and nickel zinc hydroxysalts exhibited higher extent of exchange towards chloride ions. The extent of e...
