 
 <prompt> How you fit sabi wetin something be based on how e dey look and how e dey behave? Given di last question, write one context wey get di answer. E fit be 1 - 20 sentences. Context: <response>: ```Dey get plenti important organozinc compounds. Organozinc chemistry na di science of organozinc compounds wey dey describe dia physical properties, synthesis and reactions. Among important applications na di Frankland-Duppa Reaction wey involve oxalate ester wey dey react with alkyl halide, zinc and hydrochloric acid to form α-hydroxycarboxylic esters, di Reformatskii reaction wey dey convert α-halo-esters and aldehydes to β-hydroxy-esters, di Simmons–Smith reaction wey involve carbenoid (iodomethyl)zinc iodide wey dey react with alkene(or alkyne) and convert dem to cyclopropane, di Addition reaction of organozinc compounds to carbonyl compounds. Di Barbier reaction (1899) na di zinc equivalent of di magnesium Grignard reaction and e better pass am. If water dey around, organomagnesium halide no fit form, but Barbier reaction fit still happun even if water dey. But di downside be say organozincs no too dey reactive like Grignards, dem dey expensive and hard to handle. Di ones wey dey commercially available na dimethylzinc, diethylzinc and diphenylzinc. For one study, di active organozinc compound dey come from cheaper organobromine precursors.```
