Herein, we delignated the synthesis of a novel inorganic sulfurous magnetic solid acid catalyst by immobilization an extremely high content sulfuric functionalities on amorphous silica-modified hercynite nanomagnetic core-shell via simple method. Silica (SSA) modified nanocomposite (hercynite@SSA) combines excellent recoverability and stability characteristics (which can be regarded as ferro spinel with Fd3m space group cubic crystal structure) strong Brønsted properties -SO3H groups. This was found to efficient facile for bis(pyrazolyl)methanes two different one-pot multicomponent methodologies under green conditions. The hercynite@SSA shows catalytic activity reusability in ethanolic medium among materials. A plausible reaction mechanism is proposed this synthesis.

Abstract The addition of carbon electrophiles to carbonyls and imines has emerged as a valuable strategy for the construction C−C bonds. merger this concept with sustainable cobalt catalysis yielded numerous innovative methodologies. Remarkable functional group tolerance selectivity have been observed in many cases, providing reliable methods bond construction. cobalt‐catalyzed additions carbonyls, carboxylic acid derivatives described review include earliest reports, such Takai‐Utimoto Co/Cr co‐catalyzed their progression, well modern variants, exemplified by recent Co/photoredox protocols. systematic appraisal provides clearer perspective inspiration its further development.
