Used as a Grignard reagent in organic synthesis, it facilitates the formation of carbon-carbon bonds. Commonly employed in the preparation of alcohols and carboxylic acids by reacting with carbonyl compounds like aldehydes, ketones, esters, and carbon dioxide. It is also utilized in the synthesis of complex organic molecules, including pharmaceuticals and agrochemicals, due to its ability to introduce propenyl groups into target structures. Its reactivity with various electrophiles makes it a valuable tool in constructing carbon skeletons in organic chemistry.
