Zinc isopropylsulfinate is a specialty organozinc reagent primarily used in advanced organic synthesis as a source of isopropyl radicals. It is particularly effective in photoredox-catalyzed reactions, such as decarboxylative alkylation, where it facilitates selective C-C bond formation from carboxylic acids and other precursors. This application is crucial in the pharmaceutical and agrochemical industries for constructing complex molecules. Additionally, it supports radical-mediated functionalizations in materials science, enabling the synthesis of fine chemicals and intermediates with high efficiency and selectivity.
