This manuscript describes synthesis of BF3-functionlized β-cylcodextrine grafted magnetic CoFe2O4 nanaoparticles as a hybrid magnetic nano-composite (CoFe2O4?SiO2-NH-βCD-BF3). The CoFe2O4?SiO2-NH-βCD-BF3 was fabricated by grafting of 6-O-toluenesulfonyl cyclodextrin (6-Ts-βCD) to 3-aminopropyl triethoxysilane coated magnetic CoFe2O4?SiO2 nanoparticles followed by combination with BF3. The CoFe2O4?SiO2-NH-βCD-BF3was characterized by FT-IR, TGA, VSM and SEM techniques. The feasibility of using CoFe2O4?SiO2-NH-βCD-BF3 as a magnetically recoverable catalyst was confirmed in the modified-Ritter reaction. The result showed that this novel nano-composite could serve as an efficient nanoreactor bearing super-acidic sites formed by immobilized BF3 and reuse at least for 6 times without loss in activity.

Sulfonic-acid-functionalized silica was applied as an efficient heterogeneous acid catalyst in the Ritter reaction to prepare amides by reaction of various benzylic, allylic, and tertiary alcohols with various nitriles in good to excellent yields under solvent-free conditions. The simplicity of the reaction, recovery of catalyst without loss of reactivity, high yield of products, and short reaction time represent improvements over many existing methods.

Tertiary alcohols as well as primary and secondary benzylic alcohols react efficiently with nitriles to give the corresponding amides in good to excellent yields in the presence of P2O5/SiO2 (60% w/w).

A solid acid, H-ZSM-5 (Si/Al = 37), exhibited exceptionally high catalytic performance for synthesis of N-isopropylacrylamide from acrylonitrile and isopropyl alcohol in a solid-liquid reaction system at 423 K.
PROCESS FOR PREPARATION OF TERT-BUTYLAMINE AND PROPIONIC ACID SALTS FROM N-TERTIARY BUTYL ACRYLAMIDE

Page/Page column 9; 10, (2021/11/13)
Disclosed is a process (100) for conversion of N-tertiary butyl acrylamide to tert-butylamine and salts of propionic acid. The process comprises of first selectively reducing the vinylic double bond in N-tertiary butyl acrylamide by catalytic hydrogenation of an alcoholic solution of N-tertiary butyl acrylamide to provide N-tertiary buyl propanamide; recovering the hydrogenation catalyst by filtering the solution and treating the solution with an alkali to produce N-tertiary butylamine and corresponding alkali salt of propionic acid. The process converts of N-tertiary butyl acrylamide into value added products at milder reaction conditions, without producing any hazardous byproducts and effluents.
